flippin' musical arrangements
These are flippin' awesome! Los Angeles musician, Andy Rehfeldt, took a ton of VERY well-know songs over the years and rearranged their instruments and vocals with his own music to completely change the genre of the songs.
This collection from Laughing Squid is so good you're going to want to watch all of them. BTW, this is the best the Biebs has ever sounded.
