I never had Don't Say No, but one of my old roommates must have, because I remember listening to it, and it was pretty solid. A bunch of hits, and the album tracks weren't bad, either.
In the Dark is a good song. I like that slamming intro, the contrast between it and the relatively mild verses, and how the slamming intro comes back for the break. The synth countermelody during the refrain is cool, too. I wanted to do this song back in the 80's when Billy was hot, but we already did "Everybody Wants You" and our guitarist didn't want to do another Billy Squier song.
