Rapid Fire and Steeler are the only songs on that album that I stil enjoy, I'd say. The others are pleasant enough to listen to, but ultimately nothing that I would put on on my own.
Incidentally, that's pretty similar for me with Point of Entry. The reason that I rate PoE higher than BS is because the two tracks on there that I really, really like (Solar Angels and Desert Plains) are a little better than Rapid Fire and Steeler. Still, it's not even close to Priest's best - neither album is.
