I type a line from the lyrics that I can remember in a search engine such as Google, and usually the song is found. That's how I found my childhood song Fly Away by Lenny Kravitz.
Try typing part of the lyrics into google and if you're lucky it may come up with the song you're looking for. If you need help, shout!
