Are you a completionist with your music?
I know several classic rock artists continue to put out new music and I think that's great but I don't always keep up with the whole discography. Some bands such as The Beatles and Led Zeppelin I enjoy all the studio albums. All of their studio albums have something great. I'm still building my Pink Floyd Collection. My Beatles collection is almost complete, I just need to get Beatles for Sale and Help!. Many bands/artists I like, I won't always get all their albums because I feel like some artists run out of steam after a while. I love Deep Purple but I don't really keep up with the stuff they did after Perfect Strangers.
