Playing mp3 files


I have a Moto G

Where is the best place to copy mp3 files to on the phone so that I can play them in the car.

The car doesn’t have Bluetooth, but it does have a USB port (I use a thumb drive there to listen to mp3)
so I’m thinking I should be able to plug the phone there as well to listen to mp3 files ??

Can this be done ? How so ?


Hi @davids.79kiir,

I just create a folder called “Music” and put all my songs there. Then I use Google Play music to create a playlist.

Others here probably have other preferred music playing apps they’ll recommend.

Do you put the Music folder under another or just on top ?

Also, any idea’s on how to play it in the car ?


Hi @davids.79kiir,

When I connect my phone to the computer and navigate the phone through Windows Explorer, my Music folder is in Computer > XT1094 > Internal Storage.

You’ll see something slightly different depending on your phone’s model number. My phone is the Moto X (2nd Gen).

Then to set up Google Play Music, I sign in, select “Use Standard” (because I’m too cheap to pay to listen to music) and "Done."
I tap the hamburger menu (three stacked horizontal lines at top left and select “Playlists.” I see a playlist there called “Auto Playlists” that the app has created from all the music stored on my phone. I can click to play it, or tap the three vertical dots in the bottom, right corner of the icon and select “shuffle” to hear the songs out of order.

To make sure I don’t use a lot of data, in the settings, I have “Download via Wi-Fi only” and “Stream via Wi-Fi only” checked. I also have “Downloaded only” selected in the main menu.

To build a specific playlist rather than having the app play songs from your entire collection, go to “My Library” and tap the three dot icon in the bottom, right corner of any song’s image. You’ll see an “add to playlist” option that will let you add that song to an existing or new play list.

To quickly start music when you’re in the car (or anywhere), you can add the Google Play Music widget to your home screen. On my phone the Moto app also includes an option to start music automatically when you’re driving, but the availability of that option varies by phone model.



my main issue is when I connected (via USB) to the car, the car didn’t recognize the


the make and model (with model year) trim level (if known) may help us figure this out
older radios with USB may need a simple folder structure which a smart phone can not really mimic
they may also have a size limit which the internal storage is greater than
the radio may be waiting for your phone to allow USB access (same as when connecting to a computer)


I don’t have the car radio info here(it’s a 2015 Elantra), what can I do on the phone side to allow USB access ?


ok here what I found
Some Key points

  • If the engine is started up or turned off while the external USB device is connected, the external USB device may not work. It may not play inauthentic MP3 or WMA files.

    1. It can only play MP3 files with the compression rate between 8Kbps~320Kbps.

  • Depending on the condition of the external USB device, the connected external USB device can be unrecognizable.

  • When the formatted byte/sector setting of External USB device is not either 512BYTE or 2048BYTE, then the device will not be recognized.

  • Use only a USB device formatted to FAT 12/16/32.

not sure if the smart phones file system counts as these (these are typical older file formats (used on smaller Flash drives)

  • USB devices without USB I/F authentication may not be recognizable.

  • Make sure the USB connection terminal does not come in contact with the human body or other objects.

  • If you repeatedly connect or disconnect the USB device in a short period of time, it may break the device.

  • You may hear a strange noise when connecting or disconnecting a USB device.

  • If you disconnect the external USB device during playback in USB mode, the external USB device can be damaged or may malfunction. Therefore, disconnect the external USB device when the audio is turned off or in another mode. (e.g, Radio, XM or CD)

  • Do not use the USB device for purposes other than playing music files.

  • Playing videos through the USB is not supported.

  • Use of USB accessories such as rechargers or heaters using USB I/F may lower performance or cause trouble.

  • If you use devices such as a USB hub purchased separately, the vehicle’s audio system may not recognize the USB device. In that case, connect the USB device directly to the multimedia terminal of the vehicle.

  • If the USB device is divided by logical drives, only the music files on the highest-priority drive are recognized by car audio.

the Music folder will need to be as close to the root as possible

  • Devices such as MP3 Player/ Cellular phone/Digital camera can be unrecognizable by standard USB I/F can be unrecognizable.

This could be that the phone just will not work

  • Charging through the USB may not be supported in some mobile devices.

  • Please avoid using USB memory products which can be used as key chains or cellular phone accessories as they could cause damage to the USB jack. Please make certain only to use plug type connector products as shown below.


thanks for all the info… I don’t think it’s a file issue, these files have been played before, via thumb drive.

I’m thinking it’s more on the phone side.
I can’t even get the file to play on the phone, using "play music’
Maybe it had something to do with how I loaded the files on the phone.
I plugged the phone into my PC and then dragged/dropped them to the phone.

Is there a preferred way to do it ?


That’s how I usually move a collection of files.

Are you sure they are saved as mp3 files?


Hey David, I use the drag and drop method into /internal storage/music described by southpaw. You should be able to look in that folder and see your mp3 files. I’ve also used a wireless method, installing Airmore app on my phone and installing Airmore program on my computer. The devices are connected, and then you can sync the devices and “transmit” files to the phone. They reside in an automatically created folder, /internal storage/music/airmore.

When playing music in my car, I use a couple of different apps, usually Amazon music. Google Play Music should work fine. Maybe you want to use the Downloaded Only option under Music Library.

I have a 2010 Elantra, so hopefully my configuration is similar to yours. Your Elantra has an Auxiliary port that accepts a male 1.4 mm jack, same size used on your phone. I always use a male to male cable, and press the CD/Aux button on the entertainment console. I have never used the USB port, and understood it worked only with an iPod and special cable. 2015 model may be different.


So I drag/drop some mp3 files to the phone “music” folder.

What next to play it on the phone ?

I go to google play and can see it there, but am unable to get it to play ??


Another easy way to add your local mp3 music files to google play music is uploading it from a computer. Once the music files are uploaded to the google music servers, you can see them on the google music app of your phone. You can then download them to your phone and thus can play music without consuming any cell data :slightly_smiling_face:
