Today I've got a nice collection of fantastic Floyd mashups (sorry if you already got this, blame the OCD,hehe). Add a little NIN for even greater awesomeness! The last one (audio) was made by ToTom, but the first two are debut mashups! I hope we see more from them one day (although Jamshak's is over a year old and still no follow-up).
