It was a happy song. The instrument composition remained the same until the end, which I think is good. The song didn't really have a clear melody, but that didn't matter. The song would be well suited for commercials and synchronization.
Happy Happy, Joy Joy is how I felt while listening to this instrumental track. I think this song would be a pharmaceutical commercials wet dream. I hear songs like this all the time during those types of commercials on TV.
Good job and good luck with it!
