Hello everybody,I've heard some beats that sample a melody out of a song,for instance:Four Tet-Everything is alright which samples a guitar melody I am not able to find anywhere,and I want to sample it too but the drums bother me (search the song on YouTube and you'll see what I mean),and at the end of this song the guitar melody that plays throughout the beat,I found that it is being revesed.Why do some producers do that,is it a copyright evasion trick or a stealing protection,or they just want to add a darker vibe to their beats? Thank you in advance!
