MTV has unveiled an interesting looking new online music discovery service called Music Meter . The service trawls social media web sites for emerging bands and musicians.

Music Meter tracks social media sites, looking at increasing numbers of comments written about individual artists to see who is growing in popularity. Users can checked out music videos and 30-second song samples of artists on the Music Meter site .

Once upon a time, MTV was a great champion for upcoming artists, before its programming schedule got crammed full of reality shows and celebrity spin-offs. So it’s refreshing to see the corporation investing in a new service like this.
