My bad, should've elaborated.
From your Xbone main menu
Store->Games->Search
Search for Rock Band 4, go to add-on content, then hit the "..." which shows all DLC.
They show the album covers for most of them, so that helped me remember which ones I bought. Took me an hour to go through the whole thing.
