bad-ass songs I have sung

I'm going to post Spotify links to songs I have performed in this thread. Some of them will be links to my performances; others will be links to other groups doing the songs. The common thread between all of these songs is that they are all awesome.

I am singing these songs tomorrow as part of a quartet in a recital of spirituals:

I am doing these as solos (obv in male range on the first one):

on the contemporary front, everyone is sick of me pimping this, right:
