Is there an app out there that I can download that is essentially another media player, but rather with different music then my stock app. I am looking for an app that lets me copy music to the app's library and will not locate/be associated with my default music app. I use my normal iPhone music app for parties, working out, casual listening but wanted to use an alternative app for books on tape and mp3 audio recordings of some of my classes. I just don't like the fact that on "shuffle" I could hear a song and then the next track is a lecture. any help is appreciated.
