The Hype Machine doesn't offer an Android app (although it does offer an iPhone version). This third-party option is quite solid though.
uberHype is a unique way to discover new and popular music being 'blogged' all around the world and stream it directly to your android devices. From indie genre to electronica, the uberHype app will help you find anything and everything that will tingle your musical taste buds. All the music here is tracked and aggregated by The Hype Machine platform whose goal is to empower independent voices that write about music.
