United State of Pop 2009 (Blame It on the Pop) is a mashup of Top 25 Billboard Hits by DJ Earworm. We're each going to have to evaluate for ourselves how we feel about the state of popular music, but this is a great mash-up of where we stand right now.

For more really good Mashups released over the last couple of days check out the Kleptones' new Uptime/Downtime, and the annual Best of Bootie 2009.

Also, the annual Skillz Wrap-up for 2009 which is the lyrical review of everything that has happened over the last 12 months.
