Next time you hear a song on the radio, it may just be about you. Cassie learns a lesson from the likes of Mary J. Blige, Destiny’s Child, SWV, and TLC on a new song off the Diddy and DJ Prostyle-hosted mixtape Bad Boy Presents The Preview, also featuring music from Machine Gun Kelly and Red Cafe. Following a verse from Fabolous, the Bad Girl coos over the instrumental for Mobb Deep’s “Shook Ones Pt. II,” recalling R&B jams that played out in real life. So she wrote her own song sharing her experiences and hopes it resonates with someone else.

“Who knew that they were trying to tell me about you and the crazy things you do?/ How could you be so cruel?”

She asks on the mellow tune. At the end of the mixtape, Diddy announced that “King of Hearts” will be the first single off Cassie’s sophomore album, due in 2012. Cassie f/ Fabolous – “Radio”
