It's often underrated. It's a fact that they tried to keep things mainstream with doing a quite AOR-like album with much synthetizers, but it has it's own interesting atmosphere. There are also classic-sounding and typical riffs all over the album, which is more than excellent. Hearing tunes like "Night Run", "Heaven's Gate", or "Blue" and "Name of Love", you say to yourself: "Hey, sounds like a real classic. I've heard this before somewhere."
Also, I think, if you think about music and names.. a band named UFO.. what kind of music could they play? I think this albums sound world fits the best to their name.
