The app is free and comes with 110 songs installed from 51 teams, and also sells a 250 song pack for $1.99
The teams being the cracker teams that used the songs in their cracks/hacks (ORiON, PHROZEN CREW, tPORt, DEViANCE, FFF, BRD, ect ect)
with no mention of the actual song authors.
Example: uCF is attributed to Monday when Rez made it. Turrican (Intro) and SnD.
So looks like they just grabbed some songs from keygenmusic.net and slapped them in a app and just acknowledged the cracker teams.
A screenshot in the app store displays other songs (I guess from the pack) that shows the track name, cracker team and the name of the crack.
Intriguing.
