Crunch.fm
Crunch.fm is a application that makes your Tweets more musical. By integrating the Crunch.fm application to your Twitter account, you can use their service to search for a track, listen to a stream of the track (via YouTube) and then share the track with your followers.
The application is dead-simple to use and offers a preview of the track you searched for, in order to make sure the correct stream is shared. Then the regular Twitter textbox is provided and pre-configured with the tracks name for you to personalize your Tweet with the hashtag #NowPlaying.
Once posted on Twitter, followers can then click the shortened link provided by Crunch.fm and leave comments or jive with the same music you’re listening too. Found a new track that needs to be ‘bumped’ in everyone’s car, search for it on Crunch.fm and share it.
