IDK as I agree for me there would be very little advantage. But some people like (mis)leading people (for whatever reasons.)
My two cents in regarding your ‘Flex Off’ ditty btw. I tend to prefer short(er) tracks. What I would consider with it is a bit more variation of chord (roughly) Cmin-Eb-F-CMin-Gmin-F and then return back to Cmin. Holding on the Cmin for so many bars (to give the listener a breather) gives the sense that something different is about to happen (and ‘fingers crossed’) be just as smashing as the main idea. However what we get is pretty much the same chord/melody arrangement before the ‘Cmin breather’. What I would’ve considered is to try and find a second section (but still keeping the piece to around 3 minutes.) You probably wrote it in about 4 hours, so I can understand the pretty much verbatim duplication of your main idea. As for the mixing, I can’t comment as it is not my area.
