B.o.B's fourth studio album Ether has arrived, which is his first release since leaving Atlantic Records and going the independent route, and his first album since 2013's Underground Luxury.

Lil Wayne, Young Thug, Usher, CeeLo Green, Big K.R.I.T and Ty Dolla $ign all make an appearance on the 12-track album, and Bobby said he's extremely picky about who he'll work with these days.

"All the features is just really people who I f--- with," he told Complex. "I don't collaborate with everybody, man, and I'm at a point where ... I just want to [work] with the same artist six times. I'm still going to keep doing it."
