Yes rules are great to have, don't quit, that's the biggest mistake an artist who is still growing in their creative expression can do. Keep entering and just learn to rap much louder than what you have been doing. A great rapper can be loudly vocal and still keep good rhythm and flow, your entries are too quiet not necessarily because of only your recording and speaker equipment, but a lot of it depends on your actual vocal delivery and performance which you need to work on, giving much more energy and passion in your performances like I do. I Rap like my life depends on it, if you have a softer smoother rap delivery style, you still need to convey and communicate the right level of volume, energy and use smooth transitions throughout.
I can only support Vibes music entries from my side with the whale accounts we have, nothing else, only valid competition entries.
My own personal account vote is only worth 1 penny at the moment lol
