You got the Love (Eren's Bootleg Mix) -- it could be "SOURCE featuring Candi STATON", or "Robin S"

It was 'The Source feat. Candi Staton' indeed !

So In Love with you (Full Intention Remix) -- there are 4 versions listed in Guinness[1], none of which seem likely.

The Artist was 'Duke'

Sorry can't help with the others ...
