Considering switching from iPhone to Android. When using Google Play, you can upload your current music Google Music Manager, and download it to your new phone if you like..
Easy enough. All of my music on my iPhone is purchased from iTunes and is in .m4a format. Google music manager converts it to .mp3 format. I messed around with it a little, and for example, a song that is uploaded that originally had 262 KBPS in .m4a format now 'has' 256 KBPS in .mp3 format, so virtually the same.
So my question is, should the sound quality be the same as long as the KBPS is the same (or very close), or could there be other factors that could possibly reduce the sound quality after converting to .mp3?
