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.
Process note
I came up with this beat idea by chopping some chords one day. The beat is simple but with a good arrangement it makes it makes it a smooth experience to the listener.
