Startup Idea : background YouTube player App

Problem: people love to stream music off of YouTube on their phones, however (unlike streaming music on a PC or Mac) when minimizing the YouTube app the music/video stops playing.Solution: an Application that will fetch any YouTube video or playlist and keep it playing even when user minimizes App or starts using a different App. This way the user can stream youtube music/podcasts in the background while using another app or when phone is locked.
