You have to give it a few spins, to get into the Katy B track - nothing special is going on, the simple bassline is there without any changes all through, no catchy samples. Refreshing.
Lido's EP The Passion project, well worth checking out.
Erykah's Trill friends is a strange take, repeating the same lyrics "Homeboys, and some of them we wish we never knew at all" over in a dull yet hypnotic style.
Rihanna - did she use to sing this good before?
