Amp Music Player - an alternative player without jailbreak
Some iPhone games allow you to listen to music from your library. Why not make an alternative player that plays music from the same library as the standard one? Previously, Apple did not allow duplicate functionality of pre-installed programs in the AppStore, but apparently after the release of Opera Mini everything changed. In any case, on May 24, a full-fledged replacement for the standard Amp Music Player appeared in the AppStore. Do you need a replacement for you to decide, but worth a look, especially since Amp is free.
