there should be a reason why after one thousand times hearing it i still can't memorize the refrain of 'no no never'*

Simply because, line 2 and line 7 of the chorus. Negative negation! Argh!

For those who watching, have fun tonight .. and do the line dance if it's possible. :-D

*'No No Never' is the official entry song for Germany in ESC. It is confirmed, I'm a bit obsessed and euphoric.
