I've just had a look at the 30 best Rap albums of 2014 according to Rolling Stones and which titles apparently haven't been published on vinyl. Apart from the Future and Nicki Minaj record, these are the ones I found. Wonder if any of them could fit the other clues?
Young Thug & Bloody Jay, ‘Black Portland’ and Rich Gang, ‘Tha Tour Pt. 1’
Migos, ‘Rich OFFENSIVE LANGUAGE Timeline’
DJ Mustard, ’10 Summers’
Lil Herb, ‘Welcome To Fazoland’
DJ Quik, ‘The Midnight Life’
Kevin Gates, ‘Luca Brasi 2’
Chief Keef, ‘Back From the Dead 2
IamSu!, ‘Sincerely Yours’
Boosie Bad Azz, ‘Life After Deathrow’
