I'm curious if any of you has made the switch back to listening to mp3s? If you did, which apps are you using?
For listening I've mostly used xmms over the years, but recently I've been using Audacious[2] mostly.
Back when I still used exclusively MP3s, I used Music on Console Player [0] on my personal computer and Snae Player [1] on my school's chromebook, since we were only allowed to use web apps on our Chromebooks. On my phone I found VLC [2] to be the best app since it has so many features. I can highly recommend both programs.
I still have all three installed and use them whenever I don't have internet. Although I haven't updated my local music library in a while, so I am reminded of my old music tastes whenever I open either of them.
And it almost never plays a song that causes me to hit next. Of course, it took a long time to get the channel tuned just right - but now I play music for 5+ hours without interruption of nothing but music I love.
This allows me to use Kodi's native front end when I'm listening on my home sound system, to use a web front end to play on any web-connected computer, and to stream from my server to my smartphone when I'm out and about. It's the best of all worlds. I have all the convenience of a streaming service, but I actually own the music and it will never become suddenly unavailable or replaced by inferior versions, and I don't have a fixed recurring cost just to enjoy music. Plus, a ton of great music is simply not available on any commercial streaming platform and this eliminates that issue.
I don't tend to use MP3s, though. I go with FLAC instead. Kodi will transcode the FLACs to other formats if needed.
