Some people don't know that they could be better because no one is telling them. You can't just sit there and let your friend be musically subpar. Tell'em! They'll thank you later.
Some of my musical influences: D'Angelo, Chet Baker, Nat King Cole, Jim Hall, Wes Montgomery, Drake, The Roots, Mos Def, Santana (The Actual Band), Dustin O hollaran, and Led Zeppelin. I'll name more another day.
