as a "pro" musician wouldnt you do you research on that shit LDS? you would think so huh, so u dont waste anybody's time
At what cost, though? I'm a college student, a full-time employee for a retail chain, a Siccness MOD, and a market lead for 2 cities....I forget shit often, and even if I had an assistant helping me, a lot of things would go undone as they're not a full priority.
Making songs is a small portion of being an artist. There's networking, research, development, and in Tech's case checks to write, money to keep up with, tours to be on.
Even with all those hundreds of hand between Tech N9ne, Bone Thugs, and that track, there's so many places for high margin of error. things get lost or forgotten at the expense of other things close to the artist.
