Do the research and report back.
I vaguely recall there being some limitations, i.e., if I name my book/song "I Did it for Love", I don't get to claim exclusive rights.
Now, on the other hand, if you're going to take their song title as a website name and then attempt to profit based upon the popularity of their song you may find yourself subject to other claims besides copyright.
So, do a little research and report back. Get a little, give a little. ;0)
