The only worthwhile Who albums you’re missing are By Numbers and Who Are You. They’re worth checking out but I don’t know if you'd get much out of a full discography dive.
Arcade Fire's first two albums are the only good ones imo.
Kinks I may do myself at some point, everything they did after the 60's is a complete mystery to me. I remember being surprised when I found out how big their catalogue is, and how they had this second wind in the states. Here they’re inextricably tied to the 60's.
Not sure I even know who The Feelies are!!
Last discography odyssey I went on was the solo Beatles, that was fun and I found a few records I still go back to.
Maybe you could do Zappa like I did some years ago! No having listened to him in ages I’ve been thinking of going through the live stuff I skipped, You Can't Do That Onstage and so on.
