It was cool at the Oscars when Lady Gaga sang shit from The Sound Of Music and everybody said, “oh yeah, she can sing. forgot about that”. But you can have your memory wiped and still know that Christina Aguilera can sing better than about 99% of the people who have ever lived on the Earth. That’s just pretty much a fact. That being said, she went on Jimmy Fallon last night and did “random” musical impressions. One was Britney Spears. So if you ever wondered what Britney Spears would sound like if her voice wasn’t computer generated, then you’re in luck.
