I wouldn't call it controversial, Rik. Reading the lyrics, it seems to be about a person that was cheating on a friend. Lyric excerpt:
I feel so unsure
As I take your hand and lead you to the dance floor
As the music dies, something in your eyes
Calls to mind the silver screen
And all its sad good-byes
I'm never gonna dance again
Guilty feet have got no rhythm
Though it's easy to pretend
I know you're not a fool
Should've known better than to cheat a friend
And waste the chance that I've been given
So I'm never gonna dance again
The way I danced with you
Time can never mend
The careless whispers of a good friend
To the heart and mind
Ignorance is kind
There's no comfort in the truth
Pain is all you'll find
