I'm with ya there, man.
And though I'm not familiar with Rick Astley's other songs, I will say that I do enjoy "Never Gonna Give You Up"- it's a great '80s song! (And I love a lot of '80s music in general.)
Though I still think the Rickroll fad is pretty stupid, but it's not a big deal either. It's a fun song- I don't mind hearing it.
And when I first heard the song (before I knew who Rick Astley was and what he looked like), I seriously thought that song was by a black R&B male singer-type because that's what Rick's voice reminds me of. But that's cool- he's got a great voice.
