The BQE is not an EP, mixtape, compilation, or collaboration. It's a studio album fully composed by Sufjan Stevens and the album is billed as Sufjan Stevens, not "Sufjan Stevens + an orchestra."
I would also argue that The Avalanche belongs here. It may be Illinoise's B-Sides, but it is a full studio album. And it's awesome.
Also, Michigan and Illinois aren't the actual album titles. You can leave those as acceptable answers typed in. But you should give the full album title IMO.
I only included the studio albums listed on Wikipedia, and styled them as Sufjan himself does on Bandcamp. The BQE is listed as a soundtrack album, The Avalanche is listed as a compilation album. Thank you for your comments.
