Circle Backward is a favorite, from the Live action 2nd movie. There is something about that opening guitar that makes me weak against the song. It was playing when the gang is being hunted down, having the two turn on them due to the journalist turning the against the Gang. Fred is grumpy, since he felt like he was being weak, and Shaggy and Scooby were sulking since they felt like it was their screw up.
Also right after the short flashback scene and most of the gang figure out how to take out the monsters... There is a small little snippit of a song, also by Mark Provart called "Monsters" Which I have been stalking for years and have no clue if there is a full song of it. But here are the small bit of lyrics which I love.
Here I go, it's time to show, I'm not a loser All the careless, bitter things you said. Like monsters in my head, All the words I heard you say, I could have turned and walked the other way, But I stuck around. Ill never never quit cause theres nothing to it, Ill never never quit cause theres nothing to it, Ill never never quit cause I can do it
Also the traveling song from Scooby the Musical is a fun, and bouncy romp. "No More Monsters" It's another instance that shows how close the gang are, as they sing together in the car as they drive. And specifically Velma is driving, which isn't as common as the others. (Though man, she drives scary. Going off the road and on rickety bridges. Though pretty standard for the poor mystery Machine XD) But they are so enjoying being with one another in that song, and it shows. So cute.
So sure, I love Terror time, other Hex girls songs and such. But these others are also alot of fun and catchy.
