You can also enter a phrase from the song into the "Digitrad and Forum Search" box which you will see on the main Forum page; this will in many cases find you earlier discusssions of song[s] containing that phrase. You can do the same thing with the major internet search engines, google.com being particularly wide-ranging. There is no website, so far as I know, which will do exactly what you want; there are too many songs in the world for that.
