Nicki Minaj and Cardi B are at least 2 of the people she is talking to. She was on the same label with Cardi B but was basically shelved because she would use sex to sell he music. She also was a ghostwriter for Cardi B and rumor has it that she is still owned some money!
Check out Tech N9ne - "No See Umz" (feat. Snow Tha Product & Russ), " I Said What I Said" (feat. Ludacris, Snow Tha Product), Dax - A Lot At Stake (Feat. Snow Tha Product), Merkules ft Tech N9ne & Snow Tha Product - "WARFARE"
You should check out some Harry Mack if you like the off the top freestyle shit to. Omegal Bars 45 and 52 are some good ones to really show you what he can do. Also, some Rage Against The Machine. Their music is deep and very relevant right now. For them...Down Rodeo, Darkness of Greed, Wake UP!, Know Your Enemy, Bomb Track, Sleep Now In The Fire. Those are some really good songs to listen to
