The theme is: music - new(er) and old - we heard to, at and from vacation.
This one is new(er). I've heard Cannon's "Bad Dream" once or twice before vacay, so it was semi-familiar. But highway driving is different than city driving, so I had a different kind of attention span while trekking through Virginia and North Carolina.
"Bad Dream" certainly has an ethereal quality. The synths and layered vocals remind me of something from the late 80s / early 90s of whom I cannot put my finger on.
Honestly, there is nothing groundbreaking about this song - musically or lyrically. Yet, I still like it. It's not sing-along, though I'm sure some do and will. It's just great background music.
