@ Kaifeng, good to see you on here mate :)

I'm surprised you haven't had more interest from labels for "Don't Mess", but I guess this track is quite unique, so maybe it is just too different for some labels to take a chance on. I did wonder if a couple of folks on this forum would want it for their label tbh. (Whaddya say, Oris?!)

It might be a good idea to release even just one track yourself (cdbaby etc) because then when you approach labels in future, you can show them a proven track record; that you released Track A on a particular website and sold 100 units etc. I'm sure that would improve your chances for future label releases.
