I like the backing track a lot. A looot. But to my taste the rap isn’t the best fit - the beat has a loose sort of swing feel to it, but the rap is more straight beat.

Anyway - love the track. Glad you included a couple of bars of just instrumentals towards the end. Could prove to be useful. :)

I’m always glad, when somebody use the sound effects cleverly. Just a few moment and I can imagine the enviroment of song.
