There are lots of Orange/loyalist CDs. I have two:

'52 Shades of Orange: 12th festive singalong: marches, music, songs'.
(52 tracks, but a bit of hotch-potch, including such non-Orange songs as 'Mairi's Wedding').

'No Surrender!': 14 great loyalist songs'.
(The latter includes 'Derry's Walls', 'Green Grassy Slopes of the Boyne', 'Dolly's Brae', 'Battle of Garvagh', etc.)
