I'm also thinking of selling this to companies like Grooveshark, Spotify, or a lyrics website. I really like the website myself and use it a lot, but it doesn't get a lot of traffic. It has some potential though, I'm quite sure of that, and if I ever continue serious development there'll also be an app. And yes, I know the design isn't very great, but it works for me for now.
If you have any interest, contact methods are on the website (see the "about" link at the bottom).
