What do I do if a have a melody in my head, but I don't know what song it is I'm thinking of (and I can't look it up online cuz i can't think of any of the songs lyrics)?
you have to just ask your friends. particularly the ones who are familiar with a lot of music. you can always ask me, if you want, just email me the attachment of you singing it and i will tell you if i know it, i know a lot of music
