Tubeify is your ultimate source of music and music videos.  Imagine an online platform that allows you to stream practically all and any kind of music along with videos worldwide.

The Tubeify team observed that while YouTube has embraced the music world and signed licensing agreements with all four of the major labels, the YouTube end-user experience had not been optimized for a music fanatic. Tubeify makes extensive use of the YouTube API to aggregate music content and build the world’s best YouTube-compliant music video service based on YouTube’s open API.
Launched around Christmas 2010, Tubeify works hard to reach out to all the music interested people all over the globe. Try it, test it, work it and invite your friends.
