Coming from someone who always looked for free beats to rap on, I didn't appreciate what producers did one bit, let alone did I care of the work they put in. Do you know how many beats I destroyed, and not in a good way? Now that I've put the time in producing, I realize the hard work it takes. From studying Sound Design, to learning to play the Piano/Keyboard, to learning basic Music Theory, learning your DAW inside-out, to studying the basics of Audio Engineering, to watching countless videos to learn new techniques and then applying them, to learning your Plugins and Synths inside-out. There's no way I'm giving beats away for free, a good majority of us dedicate too much time for some lame rapper to talk about his manufactured struggle, all the females he claims he's hittin', or how he's killing the rap game in his bedroom.
Let these rappers/artists put their money where their mouth is, producers shouldn't be doing $20 leases either, unless it's some basic project/session that you know is gonna sit in a folder.
