My first albums were soundtracks, as a kid. I still like the original Star Wars music (almost all the tracks) which I listened to a lot as a kid. Oh, and themes from James Bond films, and a few others – Conan The Barbarian has some good tracks, Das Boot, some of the spaghetti westerns, and some other.
If you like soundtracks, you might also try out various classical music, as it has some of the same qualities (and bits of it are often used for film soundtracks), but there’s more of it and it tends to be more elaborate and more developed.
