Interestingly enough, musician and producer Kurt Hugo Schneider’s most popular video is the same as Christina Grimmie’s. The “Just a Dream” cover, since Schneider uploaded it, has received — brace yourselves — over 70 million views. Schneider is also famously known for his collaborations with singer and musician Sam Tsui.
1. Boyce Avenue
No list of YouTube musicians would be complete without the trinity of heartthrobs that is Boyce Avenue. Composed of brothers Alejandro, Daniel and Fabian Manzano, Boyce Avenue is the most popular cover artists on YouTube. However, this group does more than just covers. Boyce Avenue has released two full-length studio albums and 12 EPs. In August, the band also released their first live album titled “Live in Los Angeles.”
