I see we've reached the whining stage. Somehow we avoided this in the US one.
Nothing keeps you from discussing a song you have later on your list. I've done it with songs that I had higher, without saying it's going to be on my list. My pick tomorrow is a prime example. Say that you love a song and why, without doing the silly "wink, wink, we'll be seeing this again" stuff. The latter means that you've (1) revealed the song is on your list without (2) saying anything meaningful about it, which is the exact opposite of what should happen.
