My Top 20 Scooby-Doo Songs (In-episode/movie songs only)

Explanation
1. Applies for animated shows and movies aired/released from 1969 through 2017.
2. These songs include only in-episode/movie songs (e.g. the "chase songs"). Opening theme songs such as "Scooby-Doo Where Are You", "What's New Scooby-Doo" and "A Pup Named Scooby-Doo" are not included. Also not included are soundtrack songs that did not appear in a Scooby-Doo movie or an episode such as "It's A Mystery" and "Those Meddling Kids". If I had a purely Top 20 Scooby-Doo songs list, all of the above-mentioned songs would have made the list.
3. #19 and #20 would have been rated noticeably higher if the songs weren't so brief in their respective episodes.
