Can't figure out song

Hmm so I just listened to all the songs on the summer part 1 and 2 albums and mustve missed this song somehow while listening for it.

I was there yesterday, August 12th. A song came on sung by a female (perhaps more than one - not sure) but the only part I could make out from the dressing room was

"I'll stay forever" or something like that. I know she kept repeating something but i dunno. It was an upbeat song.... it would've been rocky worthy. lol. any ideas? sorry for the lack of description.
