I promise not everyone on this list is a Youtube famous person. But Alessia Cara had an amazing 2017. In 2015, Cara appeared on The Tonight Show starring Jimmy Fallon and killed it, she got nominated for a Streamy award, appeared on The Tonight Show once more (this time doing musical impressions with Fallon and absolutely killed it with her impression of Lorde). Her latest hit, Stay, has become a personal favorite. I truly think that 2018 may be the year of Cara.
