Japan do seem to get bonus tracks on some albums that we in the UK don't get. More recently Noel Gallagher's HFB album got bonus tunes in Japan that were not on the UK issue.
I find it annoying tbh but I guess it's a big market over there too and it's the companies way of trying to capitalise on that.
Yeah, I think it's because in Japan, they don't have regular singles released like we do here, they do, cause some of them get released there in a Japan edition, but they're not like major releases or anything, and most of the singles we get with the remixes, don't get released there, just the odd one's, so they often package and release remix albums, with B-Sides and bonus tracks exclusive to Japan, hence why I think they have them, but yeah, they have some really unique things, the packages on them are amazing, where as we'll just get the regular CD, they'll have CD's with OBI's, snap packs, boxes that blend together to make a cover, huge booklets and things, they're just really unique
But yeah, often there are tracks that aren't even released here as a B-Side or anything, that they do often get, which is also quite unique to them
