This release is something I never would have expected from Beyonce's label, but it is a crucial release. Beyonce has had numerous club mixes of songs from her "Sasha Fierce" CD hit the billboard dance top 10, and up until now, none of those club mixes were available commercially on CD. So for you collectors of music like me who don't believe you actually own a song if you just download a digital file, this release is for you. This isn't a quick money making remix CD of club edits--most of these mixes run 6 minutes or longer, and they are NOT segued together. And for the most part, all the mixes are house/electro mixes, not hip hop. Incredible. Oh yeah, and just to sweeten the pot, you get a DVD with all the videos from the album.
