Spears Theater - A Toxic nightmare to remember

My second mash-up, Britney Spears vs Dream Theater. First of all I'd like to apologize to every single DT fan, for I have litteraly mutilated the original song. Trust me, it was really hard for me to get this masterpiece is so many little pieces. But I couldn't make somehting viable in 16 minutes. Anyways, the original songs are Dream Theater's “A Nightmare to Remember“ and Britney Spears' “Toxic“. Toxic's A capella found on 720p could look a bit exaggerated for one poorly photoshopped picture, but the sound quality difference really worth it.
