I think none of those sites measure up to Morrissey. Even if they are "official" or approved or "favorited" by him... TTY is lousy the least to say, MorrisseyMusic doesn't offer anything really interesting, none deep info... It doesn't really exist any site that gathers all the info and all the details and pics and the exclusive material we, as fans, would expect to have handy to learn more about and get to know deeper our Morrissey.
MorrisseyMusic has an elegant design to match the current album, but no real important desirable info... On the other hand TTY is lousy, ludicrously abandoned, with the only plus that they (or she) get(s) the scoop and that's the only thing that saves it... The graphic design and the content to be added sh*t and the promise to post things sent by fans are just crap, of the worst.
CONCLUSION: A real Morrissey site, as it should be, doesn't really exist.
