Re: Pick my next discography to start slowly going through
Of those, I'd suggest either the Kinks or the Beach Boys. You've already heard all the good albums by The Who (well, not counting Meaty, Beaty, Big And Bouncy, the best compilation of their early singles, and Live At Leeds), The Byrds and The Feelies (even though you've only heard one - its followup, The Good Earth, is one of the dullest albums I've ever heard). For Arcade Fire, I'd listen to Neon Bible, my favorite of theirs, but not bother with any others.
I'd probably suggest the Beach Boys over The Kinks for you, even though I much prefer the latter overall, since you've heard all the Kinks' best albums, and I'd be surprised if you like their later stuff all that much (though I would recommend a comp containing their early singles). The Beach Boys, by contrast, don't have any great albums, but there's a lot of good songs in their catalog that you haven't heard yet.
