I even re-listened to the original as it has been a while and perhaps my first impression was wrong. Nope, still not my taste but I've listened to Pentatonix's version 5x already.
And I just discovered Linkin Park's cover of Adele's "Rolling in the Deep".
Awesome. Loved the audience singing along. Usually this bothers me (see 99% of Darren Criss' live videos) but it works here.
