If you're looking for classical music specifically, I would recommend a dedicated service. For instance, I use Idagio and I'm very happy with them (there are others of course).

The killer feature is curated metadata, dedicated to classical music: searching and browsing is infinitely superior. You can select a specific work and browse all its recordings. You can select a performer and view all their recordings. You can select a composer and filter their works by type, etc.
