The vast majority of music without lyrics sucks.

Classical music would like a word with you.

Or do you mean removing voices from songs ?

Nah, classical music is one example. Another big one is techno/electronic stuff.

Contemplate Clair de Lune from Debussy, take a gander at Gwyn, Lord of Cinder’s theme from the Dark souls OST, let your mind wander at Time from the Inception OST. And that’s only the most mainstream I could think of.

Beautiful music is everywhere, from every media, in every genre, you just just have to listen.

I kind of agree with you, there is a lot of great soundtracks. However, for me a soundtrack is part of a larger medium, which it’s underscores or sublements. Most of them make medicore songs at best when listend to in isolation.
