Dunno what the first song is... I don't really listen to Talib, only my brother does haha... I have no time for much rap these days...
but #5 is DEFINITION by BLACK STAR, one of the greatest rap songs of all time (lol), and then it turns into ANTE UP by M.O.P... guess he made his own verse to rap over itor something I don't know.
Peep my Canadian rap thread.
Favourite Talib songs are Get By and I Try... and Never Been In Love... his more "accessible" songs.
