...Okay, so I cheated on the second one because Lindsey Stirling isnt as famous as Ke$ha and Taylor Swift.. <,<
Most everyone has probably already seen/heard this cover, but I'm going to put it here anyways because I like it so much. If any of you haven't seen/heard it yet, it is definitely worth listening to.
If you're into covers and you haven't heard about Alex Goot yet, I suggest you check him out. I love his voice, and the fact that he (typically) plays every instrument in the songs he covers himself. Here's a sample: Then there's Peter Hollens. He doesn't have too many videos yet, but I'm sure he'll be making more. I have Yukon1200 to thank for being introduced to him by the way. Hollens covers music using nothing but his mouth as an instrument, it's pretty freaking fantastic what he can do: He brought in a very cute violinist on this one, and it's awesome, especially because it's game music:
This is my buddy Oleyy. He are always singing while we are on skype lol ^_^ over 120k views on he's videos but he has less than 500 subs :O https://www.youtube.com/watch?v=bRpY3AizRJA&feature=channel&list=UL
Her voice is awesome: Rush covers The Beatles: I should record myself because almost everything I do is covers. I don't have a studio and it's impossible to get it quiet around here, though.
Saw a Jonathan Coultan vid above which made me think of this: I love SongsToWearPantsTo/Andrew Huang.
So interestingly enough I can sing half of the song I am featuring in this post..<,<Dragostea Din Tei covers:
