This is such an obvious call out to haters, but I think it goes beyond Mcfly haters to life in general. 'we all look the same in the dark' I always took to be saying that it is stupid and ignorant to treat anyone different to anyone else because of hwo they look or whatever because we'er all the same when it comes down to it.
The title and main part of the course I think, which is in agreement to most people commenting here, is saying that they're just another band on the radio, it's not fair to judge them because of it.
I know it's totally unrelated but 'To all of the liars who dream and conspire agaisnt the admired we hope you drop dead' always makes me thing of the git who killed John Lennon. Bringing it back to the actual song and related stuff, I think it shows how much of a vicious circle hate is. You hate people, people hate you, you hate them, they hate you, and it just keeps going round.
The first line I love so much, 'Life isn't fair for the people who care' it shows how messed up society is. Getting someone is rarely about being a caring good person. Good, caring people are often the ones let down and used.
'la temptation or music sensations/There's great expectations' I think the temptation/sensation internal rhyme is showing that there's so many ways to go in life, and one doesn't have to override the other. There's the temptation of an exstravagent la lifestyle, and there's music sensations and they're very different - stereotypically - but however you live 'there's great expectations\'.
