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.
I've sampled piano loop with Fruity Slicer, changed pitch and added effects to get a new melody with vintage vibe. I've also used Sakura and BooBass for melodical elements. Vocal is from royalty free sample pack.
