My picks:

Surely there arent many songs that fit this criteria, I could only think of Ab Soul's Outro but I think Kendrick was on it

Kanye dropping a OG Facts type single

Finished on album will be fire as well as classic album

fair enough. although the first 3 I posted are notable classics imo.

This is such an incredible song

even though Drake's vocals can be heard when Party sings "lonely"

Idk if this counts because the band is playing the instruments but Roy Harper is the lead singer on it

The intro on Vol. 2. Hand Me Down.

Hov let Bleek get busy.

Too bad YouTube has the video blocked in the U.S.

Silence

Most of Take Me To Your Leader

Damn

yessir

Bladee - mean girls

@op Solid f***ing picks. I always thought Interlude was a top 5 song on C4.

skepta interlude on more life is a heater
