Great song and great WIP, I also tried to ReMix Rowdy Rumble (a jazz mix), but it wasn't as cool as your track
The samples are great, especially horns samples, nothing to say with that.
I like the whole track, but at 3:06, the transition between the end of RR and the beginning of the other song doesn't sound good. I mean it ends quite abruptly and the transition with just drums could be better.
You don't have to cut all the end but work on this little transition and your track will be great
I want to hear more with your song, keep at it !
