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 track was made around the very catchy vocal. Lots of layers make up the bass that play along with the vocal in the drop. These are then accompanied by an analog synth lead to keep the track moving along nicely.
