Hanna-Barbera Underscores released?

I noticed there have been underscores for various Hanna-Barbera cartoons released to the public in the last decade or so.

Among them include:

"Yogi Bear"
"The Flintstones"
"Jonny Quest"
"Scooby-Doo, Where Are You!"

I am aware that many of the background music cues were likely recycled in other Hanna-Barbera toons.

I am also surprised that there is no soundtrack for "Top Cat", though it's possible that many of the underscores on that series were previously used in other toons.

Are there any other Hanna-Barbera cartoon soundtracks that have been released to the public, other than the aforementioned above?

I hope this is a sign that there may be soundtracks for "Superfriends", "Captain Caveman and the Teen Angels", "Smurfs", "Pac-Man" and "Richie Rich" someday. There doesn't seem to be very many H-B soundtracks left to release, assuming that many cues that are not exclusive to a specific show, got recycled on other series. Plus, there were fewer and fewer new H-B toons towards the end of the 1980s, and even fewer in the 1990s, as if H-B was a dying company by that point.

I also think some of the music used in the "Little Rascals" cartoon would possibly qualify for a release, if used on other cartoons and not exclusively to "The Little Rascals". The chase music heard in "The Little Rascals" was recycled in "Shirt Tales", "The Gary Coleman Show", and Season 4 of "Scooby-Doo and Scrappy-Doo". The very beginning of the Rascals episode "Science Fair and Foul" had an underscore that was also heard at the beginning of a segment on "Shirt Tales", at least that's what I found out.
