I'm in the process of backing up my files in preparation for a phone swap.

As I watch them go over one at a time, it occurs to me that one thing I've always been curious about is how the Music Player indexes sound files I just copy over USB. Anything that winds up in the Amazon Downloads folder is indexed properly, but if I just copy files over, I can only see them under "Songs".

A lot of these files do have .mp3 tags that identify composer, artist, album, etc. Some are from iTunes directories, and I copy over the directory structure as iTunes created it. But the Music Player doesn't quite pick them up.

Any tips on how to organize the directories on my Pre so it can figure out Artist, composer, album, et al?

Thanks!
