medley/not medley

Ask Katy

Why is "I Believe/All I Need to Know" called a medley?

"I suppose because they were going to be 2 separate pieces of music, which we ended up fusing in to one. But frankly, as medleys go, it is definitely lacking in a general feeling of "medley-ness". So I hereby award you one and a half gold stars for meticulous finicky detail. NR"
