Well most of the albums are pretty long in terms of number of tracks, for a start. And maybe they only want to release their best quality stuff (if anyone mentions Christian's Inferno they can suck it). Tbh I've never seen b sides as necessary, just a cool bonus. There's only really Muse whose b sides are as good or better than album tracks. What's the point in releasing cast offs they didn't think were good enough in the first place? I thought Shenanigans was a cool idea but I only listen to one song off it these days.
You obviously haven't heard any of Biffy Clyro's b-sides. They've consistently released better b-sides than album tracks for their last 3 albums now
I don't support your argument that ever b-side is inferior to the respective album it's associated with. Songs like Desensitized, Scumbag, and Too Much Too Soon are worthy of their place in any Green Day album.
Music purists might but in terms of mainstream commercial success b-sides aren't in vogue. Ask most young people who spend money on music these days about b-sides and you just won't get the same familiarity or appreciation of them as you would with older generations. I know vinyl sales are on the increase again but my point was that there's no focus or attention put on b-sides anymore and that GD's lack of output there might be an administrative/financial decision rather than any creative standpoint from the band.
Again, I simply can't agree with you. People who are very into music invariably explore the b-sides of artists as a matter of course. B-sides aren't released for the casual fans who might buy one or two songs of an artist of iTunes, they're for people who genuinely enjoy and follow bands and are intimately familiar with their back catalogues.
And if Green Day can't afford to release vinyl or b-sides these days, I don't know who can. They're probably one of the richest bands on the planet, even if they made a complete balls of something they have the nest eggs of Dookie and AI royalties to fall back on. Besides, as I've mentioned before, Biffy Clyro are prolific in their release of b-sides, and they're on Warner too.
May be he writes but not all get recorded
If a song is good, record it. It's not like money is an issue to them.
Maybe some of the unreleased songs are Love Songs and he might want to keep them personal and private. Or it might just be a Hit and Miss or the record label possibly putting their foot down - who knows. But bet there are ones that could be released - maybe they are just waiting for the right time....like Good Riddance etc
If he's willing to release songs like When It's Time and Good Riddance, I don't think there's much more in the way of sappy love songs that could be too private to release.
