I think i understand the switches in the beat
In my own productions i wanted more of a soundscapes experience and an extension of the song to take its own course outside of the song ( i also had a thing for a song ending at 3:46 cause of Afrodisiac)
so when i created it i created like 3 different drum beats 2 extra sections that really didnt have much to do with the song and sometimes and tho it all sounded good
for the song it wasnt really the tea but it sounded good on its own and after all my work of building and creating the tracks i didnt wanna just deleteit so once the song ended I added it at the end for a vibe out until fade out lol
so i think thats why we have the beatchanges not to lose the origina visioon of the track but still giving the song whats best for it
