As a couple of others have stated, it feels more and more like Rebecca Mayes genuinely dislikes gaming in and of itself. It's not the same good-natured fun as when, say, Yahtzee rags on the Total War games for being "glorified spreadsheets." There is a palpable disdain for gamer culture in Rebecca's songs that becomes evident the more one watches.
As for her writing and singing, I'm not sure what people seem to be raving about. I'm actually a big Indie fan, and her style falls squarely in the generic category for me. She's pretty, though, so maybe that's part of the infatuation.
At any rate, I'm not sure if Rebecca Mayes Muses is something the Escapist should continue to run. I won't be watching again.
