I prefer the layout of recordnerd more than cd-tracker but adding my list that i had from MA was so much faster using cd-tracker that i had no choice but to use it. I left MA because I didn't just want my list to just be metal. One of these days i'm going to switch to rateyourmusic.com I think that's actually the best looking site ive seen yet and it's pretty cool that it has a community as well.
