Hating to go on a tangent in a great thread, but I gotta be that guy.
Making copies of music you bought for your personal consumption on different devices is protected in the USA by law, and I think that I am safe saying that that extends to other countries.
Indeed, you bought a license to use that music.
However, if you loose all copies and hit the internet to replenish your copy for free, you just crossed over into engaging in illegal distribution and that's the part you can't defend against in court. And the RIAA is ever watchful.
That's all completely different in China where mikedt lives, so check your local laws. What I've described applies to most of us, so please exercise caution in the face of the law.
OK, now that I have been that guy, let me make up a little.
If you have a library of Apple lossless music and don't want to transcode it to something smaller, 3rd party players are your friend. Meridian will handle those for sure, and I think Rockplayer and Moboplayer will as well. (I used to know that answer for FLAC and ogg vorbis, but I forgot. I think that those are handled...)
AAC is a proper free codec, if your version of Android won't handle it, again, Meridian and the like will. Tags were already covered, I can't add to that.
Hopefully I didn't duplicate too much info there.
As a huge Magnatunes fan, I can chip in another resource, free and legal -
Royalty Free music downloads | Jamendo - Jamendo
Last I checked, MP3s only, but a great place to check for out of the way artists and some great music. I have a number of piano solos from there, wonderful performances.
Hope this helps!
