Finding songs with only one or two of the lyrics... oh fun! lol

So in the last two days I have managed to find two songs just based on only a few words.. and that was not as easy as I thought it was going to be... yet why did I think it was going to be easy to begin with? Thanks to my friends and the internet however I was able to find them. They aren't the most popular songs in the world either but they were stuck in my head so what else could I do. Once a song get stuck in my head its hard to get it out, especially if I only know the beat of it.. then I go and listen to it a couple of times till I'm sick of it. I'm sure this happens to lots of people or maybe I just go crazy. Its funny some songs I can remember perfectly in my head I try to sing them or write them out however I mess up the lyrics or something. Its like I have a built in radio in my head its awesome...and no I'm not crazy.. only slightly. Well kiddies! I'm off to bed because well sleep is very important for this one's brain to process things.. and that maybe just something useful for first day of classes!
