I'm a weirdo that loves Crash Love and also Art of Drowning too. I feel fine with loving Crash Love too when I bought an old copy of Answer That and Stay Fashionable and the cashier said "ah, when they were still good" ...fuck off, cool guy. So yes, AFI please keep making records.
I know that feel. I was scrobbling Shut Your Mouth and Open Your Eyes, which I love, on last.fm recently when someone attempted to give me props for listening to AFI "before they sold out and turned gay." Hahaha oh god. It's like fuck off man, I'm not a philistine like you. I love the wintry atmosphere on Decemberunderground, and Crash Love-era songs like Torch Song, End Transmission and Too Late for Gods are some of my favorite stuff they've done.
Anyway, Sing the Sorrow is easily a Top 3 all-time record for me. Maybe #1.
