Fair question.
I recommend buying as little as possible from the major MSM music companies. When doing so, be frugal and download individual songs.
Explore older stuff. There is so much available from the entirety of recorded music history nowadays.
Current product is not the best, although there is always the rare good stuff.
I have everything from Elmer Berstine, Jerry Goldsmith, Hans Zimmer, Bernard Hermann, Ennio Morricone, John Williams, etc.
I think to just dismiss Howard Shore without listening is your choice, but is not legitimate to call it junk.
