"Z Best Summer Ever" is heating up with some hot new music this week!

This might be THE breakthrough hit for 5 Seconds of Summer. This one has smash written all over it.

After all kinds of legal and personal troubles, Robin Thicke could use a hit and this funky jam with Flo-Rida could be it.

Jason Derulo follows up the #1 smash "Want You To Want Me"

Zedd is back with singer Jon Bellion.
