Ok I registered here extra to solve the 6th one. It's name is "Cover girl" which had it original appearance in Terry Pratchett's animated series "Discworld".
Haven't checked your other songs yet but anybody who liked Buddy must be on the right track says I.
Really a shame we aren't supporting that sort of music in the world, oh and if you by any chance have some similar songs like that, I listen to Dire straits and Huey Lewis and the news, Bryan Adams, Ratt... I know I probably overdid it with the names but I somehow hope you can recommend your personal favorites.
Cheers
