Huge progressive metal Spotify playlist with almost 5,000 tracks.

Wikipedia describes progressive metal (or prog metal) thusly:

"Progressive metal (sometimes shortened to prog metal) is a subgenre of heavy metal, which blends the powerful, guitar-driven sound of metal with the complex compositional structures, odd time signatures, and intricate instrumental playing of progressive rock. Many progressive metal bands are also influenced by jazz fusion and classical music. Like progressive rock songs, progressive metal songs are typically much longer than standard metal songs, and are often thematically linked in concept albums."
