Prefer ID3v2 tags over ID3v1 tags and APE tags on MP3 files
It seems that when a file has both ID3v2 tags and ID3v1 tags, Rhythmbox currently prefers ID3v1 tags or APE tags and ignores ID3v2 tags. This doesn't seem to how other apps handle it, including iTunes and ffmpeg. I believe both of them prefer ID3v2 tags on MP3.
