Just when you thought that you didn't need another search engine, a couple of folks have gone through the trouble of creating one. Musikki is a music search engine that aggregates all of the info on your favorite band and artists in one place.
It's a little slow-going at first, but once you've typed in an artist, you're given music videos, concert updates, bio, discography, and many other things.
Musikki isn't anything elaborate at the moment, as the company is still in a beta release stage, but they do have plans to roll out more features in the future.
My guess is that lyrics will be one of the first things they add since that's a high-demand item that anyone using a music search engine would expect it to have.
It isn't revolutionary, but it's still worth a mention.
