I downloaded the app too, it's really pathetic to use other people's work to make money
1) musics are used without permission by some little wanabee ripper/lamer who want to be 1337 h4XX0Rz by releasing Justin Bieber mp3
2) ALL credits from the stolen music are REMOVED or (worst case) replaced by those LAMER'S name and/or groupname
3) some poor no-life got all that rotten keygen/infofile and make a site to put all the songs with lamer's groupname as author name
4) an emperor of lame ripped the rippers and used all the stolen data for his shitty iPhone app.
I hope some of you have a contact with people at Apple!
And yes, there's one of my chiptune in the "free" (haha) pack, it's my "little swedish boy" old .xm
