Hey so I was wondering how to throw in lyric rips from say the 90s and before to modern day songs. For example, axwell's heart is king with losing my religion; It sounded so natural.
I want to do like a nudisco/indie dance song with a kung fu fighting acapella and I'm also looking for a prog house song to do with bowie & queen's under pressure.
Is more rigorous editing needed besides trying to juggle cue points and altering the tempo of one/or the other needed in order to get something that sounds "right?"

Thanks for any input
