three little mash ups, 2 of which work brilliantly, one of which is an overload of cheese...  

You can make any stupid rap song sound great with that Back in Black riff... Still it's an insult.

don't agree Nelis - Although there are some awful mash ups with back in black, Jay Z is actually quite good!

Though my favourite of the 3 has to be the great Trent Reznor vs the not so great Beatles!!

JayZ - its actually pretty good...ACDC rocks no doubt about it..a classic in my book... a lot of JayZ tunes his stuff kinda sticks to ya after you hear them you wanna humm it or sing it later.. he also did a rap called a it s a hard knocks life with a sample from the broadway play annie in the background. But of course if you don't like rapp I can see how someone wouldn't like it...but believe it or not a lot of new genners like the mix I think it's an age thing maybe...
