In The Alarm's case, they wrote music about a subject they were passionate about and it comes out in their performance. I like Mike Peter's voice in a way that I don't like Ian brown or Paul Weller's voice (although Weller did go on to make an excellent solo album in Wild Wood) and the band have a big sound that I like. They also achieved what they did without a loud of journalists ramming it down people's throat, and that can be said for a lot of bands.
On "Spirit of '76", they are closer to Springsteen than U2 (and Springsteen is my number 1 artist) and on the Change album, they have a huge guitar sound which sounds fantastic. I didn't have them in my 15 by the way, but they'd be in my top 50. I think their music is rooted in rock and roll in a way that The Stone Roses isn't, and I'm more often than not, I'm going to like a band with that sound.
Look, I accept that I am in the minority and as I said, I have no problem with The Stone Roses being in there. It's just that I can't think of a wider gap between output /achievement and adulation in modern rock and pop. I would rather say these things than just label things as "shite" or "best ever" without any context - I don't expect people to agree with me.
