I can't stand 'Last Christmas' by Wham! Its Awful. [/quote]

I was shocked at first!
But it depends on your proximity to it I guess, like perhaps you heard it too many times and it annoyed you, or maybe you associate it with bad things, or you didn't like it the first time and never gave it a chance since. Songs are like that. For me, songs tend to just grow on me eventually, whilst others I love straightaway and never stop loving. That's just me personally though..
