I looked at covers of the HT EP, and the back cover is long and thin, and it looks like a cover of a tape. The front cover, though, has a CD shape... So was the EP published both as a CD and a tape?
No, I have the Xero cover [it's a blue cover with a baby on it]; I also have the back cover of the EP, it's the same color as the front cover, and the names of the tracks are on it...only that it's long and thin, as in a cassette cover... If you have the EP, I think you'd understand me...
