Ollbeat

Ollbeat is a social music app, making it easier to follow the music your friends like. It works by connecting to each user's Spotify account, and automatically sharing the new likes to all your followers in a Facebook-style feed. Then, other people can listen to the music clip, like, or comment on the shared song.

It's a great way to discover new music, stay up to date with your friends' musical taste, and also engage in a more meaningful conversation about music.
