Awesome A Cappella Songs

Awhile back, I posted a collection of amazing cover songs I found while surfing around on YouTube. Well, this post is similar to that (and actually includes some of the same artists as the original post),  with the major difference being that all 10 of these songs are performed entirely a cappella – that is, without any accompanying musical instruments. Since most of these songs are also covers, I've included the names of the original artists (in parentheses). Enjoy!  ~  JH

1)  Pentatonix  ~  "Thrift Shop"   (Macklemore & Ryan Lewis)

2)  Acquire A Capella  ~  "Sail"   (AWOLNATION)

3)  Mike Tompkins  ~  "Fireflies"   (Owl City)

6)  Shane Stever  ~  "Your Love Is My Drug"   (Ke$ha)

7)  Michael Flayhart  ~  "Blurred Lines"   (Robin Thicke ft. Pharrell & T.I.) (BTW, this is a highly sanitized version of the song – nothing overtly lyrically or visually offensive here)

9)  Kurt Schneider & Sam Tsui  ~  "King Of Anything"   (Sara Bareilles)

10)  Justin Bieber ft. Boyz II Men  ~  "Fa La La"   (Bieber's own song, apparently)
