Tomahawk

I'm both very intrigued and very skeptical of the promises of the Tomahawk player. It's an app that ties in multiple sources of music content (local library + spotify + soundcloud) into one central repository. It even has a social layer where you can pull in Facebook music wall posts or create radio stations from obvious sources like last.fm or This Is My Jam. It does alot... and that's where the intrigue and the doubt come in. Maybe too much? I'm willing to give it a whirl but sometimes less is more! Anyone given this a spin?
