This is pretty good but they should just PUSH Bad Girls, it's fantastic.

IKR?

This song can smash, it's so good

Good timing for the second single, hopefully they can regain their momentum. They don't deserve to be a one hit wonder.
I'm not crazy about the EP so far though.

Had a feeling this would be the second single

Is there any other evidence apart from one tweet that could mean anything?

"surrender your heart" is part of the lyrics of the song, they are already confirming it plus an unreleased pic of them with the tweet

I absolutely love these guys, just met them earlier this month, the EP is fantastic, but I feel like they could have a hugeeee hit in Just Imagine It!!!
