I COMPELETELY FORGOT THAT IT WAS POSSIBLE TO GET A BETTER INSTRUMENTAL/ACAPELLA FROM THIS SONG USING OUT OF SYNC VERSION WHY I AM REALIZING THIS NOW??
Anyway it's not an almost clear acapella because not only vocals were out of sync in that version. Guitar riff in the beginning(which i removed) and drum kit were also out of sync. Therefore, it doesn't sound like it should.
Anyway here's download link: http://www.mediafire.com/file/d71c6advz67ta8c/My_Little_Pony_Friends_Acapella.mp3
