What is the best way to find the title of a instrumental if I dont know the artist or title? It's killing me.?

well that's a hard one i have no clue...but if you had a verizon cellphone you could use the feature that id's the song that is playing which has been really helpful...then again im Pretty sure other cellphone companies offer that feature and the best part it's free...i don't know if it's much help but yeah. well good luck in finding the song :)
