It's mashup week. I'm not a fan of mashups for the most part. While the slightest incompatible detail breaks the spell, sometimes enough work/luck produce an interesting take on two well-known songs. Too often, though, they're generally just lazy attempts to capitalize on novelty. The mashups this week are mostly pretty good as in they're done really well or they are particularly clever. See if you agree. Or don't. I'm not telling any of you robots what to do.
