From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

128kbps mp3s are terrible
You are correct and I don't normally like to listen to anything less than 320kbps. BUT, my phone does not have expandable memory so it's hard limited. And where I listen to most of my music while travelling is in the car using the car's speakers which aren't going to make much difference listening to 128vs 320. Even when streaming music, I'm not going to get 320. I may go up to 192kbps instead of 128 but I doubt it will make much audible difference with shitty car speakers.
If your device supports it, you might want to encode to Opus instead. Opus produces much higher quality files at much smaller file sizes than MP3.
For example, Opus at 128kbps is considered transparent when compared to the source file. You can probably go down to 64-96kbps when its just for playback in your car.

As for transcoding them, you might want to check out ffmpegfs: https://github.com/nschlia/ffmpegfs
It can create a "virtual" drive based on your source files and automatically transcodes them when you drag & drop files from there onto your device.
192 is okayish imo
