Ain’t No Other on ZonTube
The idea is simple. Start by browsing huge catalog of music by artist, album, or genre, or just search the catalog for an artist/album/song. When you find the artist/album you’re looking for, ZonTube brings up a track list, and then makes an ajax request to search YouTube for videos of each track. If there are YouTube videos for a track, a play button appears next to the track name.
Click the play button to view videos of the song. Sweet!
As you can see if you play with this a bit, when you click on a track name, some garbage / unrelated videos come up, but out of the top 6 most of them are usually relevant.
Bottom Line: If you’re searching for a specific video, you may be better off going straight to YouTube. But, if you wanna browse around for videos by genre or artist, give ZonTube a shot.
