For some artists, I own everything they’ve ever released. If a new album comes out, I’m going to buy it, no matter what. With others, it’s more sporadic — I’ll own the “important” ones, the most beloved or critically acclaimed.
Then there are the one- or two-album wonders, performers who have extensive, well-respected catalogs but who for some reason never captured my attention enough to take hold. Jackson Browne and Tracy Chapman are great examples who leap to mind.
