As far as I know, it's not an album. It's an E.P. the definition of which is here:
An extended play (EP) is a vinyl record, CD, or music download which contains more music than a single, but is too short to qualify as an LP/album.
That's why it seems a little short. I must admit that this listing in its current state, is misleading. It's RRP of £7.99 (pretty much the cost of an album) can only further increase the confusion.
