Jessica Anne Newham is another YouTube success story. The Aussie, who records as Betty Who, went viral when her roller-rink nugget "Somebody Loves You" was used in a flash mob wedding proposal filmed outside a Home Depot in Utah. Yep, that old success story. The 22-year-old's positive electric groove brings to mind Robyn and Pink, with all the added club and beach smarts of the Sydney scene. It's pop music that doesn't willfully insult your intelligence. Frankly, she sounds remarkably like Katy Perry, if she didn't want to make you puke cupcakes. Since her last time here, in January for Tomorrow Never Knows, Who has released a new single, "Heartbreak Dream."
