"Spec Ops: The Line will no longer be available on online storefronts, as several partnership licenses related to the game are expiring."
Music has indeed been the cause of games being delisted before. It could also be guns themselves in the game as their likenesses and names also have to be licensed from the manufacturers.
Licensing costs money and I don't imagine Spec Ops has enough appeal to make it worth the cost in 2K's eyes.
