Help me find these essays about cover songs

The first one is a 2006 end-of-year piece that talks primarily about the phenomenon of Gnarls Barkley's "Crazy" and how it spawned all sorts of cover versions, but that the vast majority of the artists covering it were white. It also just talked about the ramifications of indie artists covering pop songs in general. I want to say it was in PopMatters or something like that.

The second one is an essay that was written in the 1990s but never published anywhere (just put online recently), and I read it because it was linked somewhere. It's also about the phenomenon of indie bands covering pop songs, and it begins with how the writer was a huge Replacements fan in the 1980s and didn't know what to think when they covered "Black Diamond," since KISS represented everything that he and his friends were against.

Usual search terms aren't working for me, so hopefully someone knows a bit more about these essays so I can read them again.
