Big Sean is often heard saying " west side " in his songs; he is referring to the west side of his hometown Detroit, Michigan. In his later years in high school, Sean gained a valuable relationship with Detroit hip hop station WHTD; he would show his rhyming skills on a weekly basis as part of a rap battle contest held by the station. In 2005, Kanye West was doing a radio interview at 102.7 FM. Hearing about this, Sean headed over to the station to meet West and perform some free-style. Initially Kanye was reluctant to hear the emcee, however he gave Sean 16 bars to rap for him, eventually according to Big Sean "As we get to the entrance of the radio station ... we stopped in the middle of the doorway. He starts looking at me and bobbing his head,". He left a demo-tape as well. Two years later, West finally signed Big Sean to GOOD Music.
