Twitter’s music discovery app is finally here so you can join the likes of Moby or Jason Mraz in singing (or tweeting) its praises.

The mobile and web app is similar to the Hype Machine:

Today, we’re releasing Twitter #music, a new service that will change the way people find music, based on Twitter. It uses Twitter activity, including Tweets and engagement, to detect and surface the most popular tracks and emerging artists. It also brings artists’ music-related Twitter activity front and center: go to their profiles to see which music artists they follow and listen to songs by those artists. And, of course, you can tweet songs right from the app.

Users on iTunes can only hear song previews so log in to Spotify and Rdio to hear full songs.
