I bought it. Of course, I never got the idea of a "Rick Roll".
Astly is a good musician with several hits.
I bought it. I'd buy it again just to make up for Numskull not buying it.
Guitar, Bass: Hard/Expert
Vocals, Standard Keys, Pro Drums: Medium/Hard
Pro Keys, Pro Guitar: uhyeahrite
Thanks to the OP's recommendation I bought the song and made Rick that bit richer. It's a bit tough on keys due to the four note chords of evil, but it would be fun if you were good enough. I like the surprisingly funky bass line - pity there's no pro part for it.
I've not even sung it yet and already feel like I've had 2 dollars' worth of fun (at current exchange rates)
I can't say I understand why anyone would suggest that ANY song could be a "bad idea" to have in RB, let alone what was the #1 requested song at the time. You know, it's not like Rick Astley wrote and recorded the song with the intent that it would become an internet meme. It's a piece of music and that's what RB is about. This post, however, would have made at least some kind of sense (maybe) if the song had been released somewhat more recently.
But I believe in this and it's been tested by research: he who  nuns will later join the church.

I'm not trying to change anyone's mind here. I hate the song, but I can coexist with people who don't. I'm just pointing out a mistake that people keep making. The most requested song is not necessarily the song that the most people actually wanted to play.
