Singer and multi-instrumentalist Steven Wilson named Partridge one of his favourite songwriters of all time: "What I love about Andy's music is that every song he writes has a very strong concept or idea behind it. He's not just rattling off love songs or songs about how lonely he is. Every song has a little twist to it, and it's so clever, so smart." His favourite XTC albums are Drums and Wires and Black Sea.Take Away/The Lure of Salvage (as Mr. Partridge, 1980) - remixed, redubbed and reprocessed versions of XTC material
