Dance Central 2 is getting a couple of legit tracks over the next few weeks. Chris Brown's "Yeah 3x" will be available for download tomorrow and Janet Jackson's "Nasty" joins the lineup March 27. Another of Jackson's early hits, "Escapade," will also be offered in the Xbox Live Marketplace that same day. Each song is priced at the usual 240 Microsoft Points (or $3) and the Janet Jackson Dance Pack 01 is also discounted at 440 points, or $5.50.

Now there are a couple of blasts from the past. When these Janet Jackson songs first came out, Back to the Future Part II was just hitting theaters and people who weren't total computer nerds knew what DOS was. Really makes you think. Not really, but it's cool to reminisce, isn't it?
