We see a lot of mashups (our directory lists over 4,300 mashups). Lately we've noticed that they've moved beyond your ordinary application. Here is a quick overview of some recent additions that are fun and useful.
Vadio is building a business off the YouTube API. The company also has its own technology for translating a list of songs into music video playlists no matter where the videos are stored.

BandPage creates a platform where musicians, fans and others in the music industry can interact easily. For musicians, it can be difficult to stay connected to fans who are scattered all over the web. BandPage aims to rectify this issue by providing musicians with a one-stop-shop solution; update once and publish everywhere. Bands simply create a BandPage profile and all their info is updated across various other online channels as well. The BandPage API allows third party developers to access this data and integrate it into other applications.
