Quoting:
This Smiths' song is about solitude and failure to meet someone to love.
It's a world wide hit besides speaking about gay relationship.

Who says it was speaking about a gay relationship? "How Soon Is Now" is about loneliness and the longing for companionship. Morrissey does not speak of any particular gender...just "somebody." He is also speaking universally (meaning he is not just speaking for himself, but on behalf of lonely people everywhere), so how could he have just been speaking of a gay relationship? As for it being a "world wide hit," well, it didn't exactly chart very high, did it? It's certainly The Smiths' most well-known song though, but I really don't know how much of a hit it was in its time. It's just one of those rediscovered treasures. Now if only some of their other songs could gain the same notoriety...

They were cool like other gay groups: Erasure, Soft Cell, Pet Shop Boys,...

(Well, I think I had to write it to show I don't have anything against gays or whatever...)

If you mean "gay groups" in that certain members of the groups were gay, well, your examples are accurate; Erasure and Soft Cell both have gay men as part of them (Andy Bell and Marc Almond, respectively). I'm not sure about Pet Shop Boys. But how can you call The Smiths a "gay group" in the same respect? Morrissey has never, even to this day, confirmed his sexual preference, and he'll probably take it with him to his grave. Yes, there are certain songs ("This Charming Man" being a great example) that would seem to indicate that Moz is gay, but he has never actually come out and said that he is. He never proclaimed to be anything. People can speculate all they want about him, but he's never admitted it...unless I've missed something.

If you mean "gay groups" in that these groups, The Smiths included, had a large gay following, then I'd say you're right. But I highly doubt that every boy that would climb the stage to hug Morrissey...even now...is gay!! :) You can put Depeche Mode in this category as well, since they have a huge gay following...and none of its members are gay themselves.

I am not particularly a Smiths fan, but I do like some of their music.  I am straight and don't really think of gay relationships when I know that gay artists are singing.  I appreciate good music for what it is:  good music.

I believe that is the right way of looking at this issue.

I used to get a bit bothered by the fact that a lot of the music I love is from gay people - a lot of groups mentioned above. I love a lot of Stock, Aitken and Waterman's music not realising that it originated from something called 'Gay Disco'.

Now I just think 'I like the music' and that's that. I can't change what I like.  :D
