Is this already a song?

Hey. I know that you peeps don’t dig my tunes s’much, but I was venturing into melodies, but I want to make sure that I don’t just have the melody from some song that I have forgotten was a song…do you know what I mean? Basically jsut listen to this and tell me if you have heard it before. If you have then please let me know what song. I would feel like a jackass if I made a song and then had it just be a slightly varying version of someone elses.

**It’s just the melody scratched out in one record…so not that great, but tell me if you’ve heard it somewhere.
