Boy George - Do You Really Want To Hurt Me (acapella) (from 1982)
Bruno Mars - Finesse (instrumental), slowed down 5,6 percent so 1 semitone to E minor (from 2016)
Cut off the acapella intro, used the outro (minus the very last words) as intro, filled the gaps in vocal with multi delays (with volume automation) on words, for instance the 1,2 (see mashup title).
Lots of small timing fixes in vocal.
