People might scoff at YouTube fame, but in the case of Julia Nunes (and countless others), it not only pays the bills but has allowed her to crowdsource funds for her last three albums via fruitful Kickstarter campaigns. While she’s not banking millions, enough people have been paying attention that she can enjoy a career as a working musician, singing in sleekly pleasant lower intones and flexing her instrumental chops (she plays the ukulele, guitar, melodica, and piano). She has a new six-track EP, UGHWOW, which is led by the out-of-love synth pop scorcher “Used to Want.” by Leilani Polk
