Cassie is co-hosting The Morning Showdown the week of April 2nd, from 6AM! Grace Valerie kinda killed it with the votes last week-- 69.8% and heavy voting. But here comes Cassie with a R3HAB remix of her new single "King of Hearts". It's a dangerous track. We're scared. And we can't wait. Remember toÂ listenÂ Monday through Friday-- and you can vote once-per-day!
