All the instruments, melodies and arrangements have been 100% made by the producer. No free-royalty use loops have been used to create any part of the instrumental of this track. There can only be loops only in the drums section (claps, shakers, top loops, etc) and ambient or vocal samples as a support of the production arrangement.
This song is made by little, sweet and simple things, it has one single synth chords with two layers, a mid bass starting from the build up and ending at the end of the drop. And the main vocal is singing: "Yeah, we're going on all night."
