DeadlyRamon: A rhythm game that doesn't let the player use his own music, whether on local storage or streaming, is worthless to me.

Then most have been worthless to me for a long time.
Last one on which I gambled was Dead as Disco. I uninstalled it after learning that the main campaign was locked into the game's original soundtrack, but at least it has a non-campaign mode where one can import his own music files/streams.
