Staples has two albums available on Spotify, 2014's Hell Can Wait and 2015's double album Summertime '06. Summertime appears to be a biographical album of sorts, kind of like the Good Kid Mad City-type stories of gang-banging and life getting by in the 'hood. According to Wikipedia, Staples is actually a Crip (a Naughty Nasty Gangsta Crip). So, make sure to wear the right colors this year at ACL, or at least avoid the Bud Light Lime-a-Rita Stage when Staples is playing.
His most-listened-to song on Spotify is "Blue Suede," from that 2014 EP, with almost 3 million spins.
"Senorita" from that new album, with just under 2 million listens, is the most popular from the new disc.
