HELP PLS? [blake's group in the carnival]

hey, i live in SE asia and here, they've just aired it so the last episode was the 3rd season.
i just watched it and i'd like to know the title of the song Blake's group danced to at the carnival.
i'm not sure but i think the lyrics were a bit seductive. the song started pretty slow but was pretty fast in the middle.

and if you dont mind, i'd also like to know abt the song that jersey n nolan's group danced to.
