The work is good. The interface isn't very polished, but it sounds like you haven't really worked on it yet, so I assume you'll polish it up later.

On the copyright side, there have been issues in the past (http://news.cnet.com/Lyrics-site-negotiates-copyright-issues...). I'm not sure how they were worked out, or if a defense of "everyone else is doing it" justifies reliance. You should look into any updates in the area, and also be aware that one day someone might disagree with you on if its ok (and by disagree I mean sue).
