um.... there must be something in the song that can make you guess at a title. If not take a line of lyrics and type them into google and you should come up with a song title ... to find the particular artist might be harder but a Limewire search will probably come up with a few versions and ... I'm assuming that you have obtained an in correctly labelled one you should be able to work out who the artist actually is . I have only failed in this on a couple of occasions.
I hope this helps
