There are mash-ups, and then there are mash-ups.
This particular one falls into the latter category, as some genius/musical Dr. Frankenstein by the name of Neil Cicierga has somehow managed to splice Metallica's metal classic Enter Sandman with Hall & Oates' '80s pop tune I Can't Go for That (No Can Do). The resultant track is called 'I Can't Enter That (No Sandman)'. Of course it is.
It's pretty darn brilliant and is well worth three-and-a-half-minutes of your time.
Happy Friday!
