The site has a huge number of TV theme songs and other associated music, such as end music or assorted tunes sung on the show.
What got me is that finding some of these pieces from my childhood that I haven't heard in decades really made me feel like I'd been transported to that much younger me. I was very impressed. Music from Rat Patrol or Secret Squirrel? Really? Yes, really.
So I've downloaded a mess of music from there, and thought I'd share to any who might find it as much a walk in the past that I did.
