Battle Of The Summer Jams: Demi Lovato Vs. Jennifer Lopez

Welcome back to the Battle of the Summer Jams were are letting you determine the song of the summer by putting two songs in a face off until reach a final winner. This week Demi Lovato and Jennifer Lopez are stepping up to the plate. But first we need to look back on last week when newcomers Becky G and 5 Seconds of Summer offered up their catchy tunes, "Shower" and "She Looks So Perfect." Becky G dominated the battle, taking 76 percent of the vote. She'll join Katy Perry and Ed Sheeran in the winner's circle. So who from this week will join them?

Are you feeling Lopez's dance ballad, "First Love," or "Really Don't Care," Lovato's infectious kiss off to an ex?

Now that you've had a chance to listen, it's time to vote, which you can do plenty and often as you like until next Thursday at noon.

And if you feel that you were robbed in the previous battle, fear not, because 5 Seconds of Summer will join the previous week's losers in a redemption round later this summer.
