Probably the odd man out these days, but I don’t use music streaming apps on my phone, per se, and I do have a couple of HiRes music players I use on occasion, mostly at home. However, those players are not safe with their little screens and having to scramble to pause if a call or text comes in while driving (no Bluetooth). Not to mention that streaming apps like Spotify or Pandora require using data on the road, as far as I know.
Well, now with my Moto X4 I have discovered a solution: Onkyo’s HF Player app. I even dumped some 24/96K FLAC files on the microSD card and the app plays them, too! Very cool. It may not play them at that resolution, but I don’t care when I am driving. Artwork displays, too. Tried a couple of other apps, but this one seems to be the answer for those of us old school-type listeners
