There are cover versions of popular songs on YouTube? Who knew?! Although if we’re honest, what’s surprising is that someone launched a startup devoted specifically to them. It’s called – and please stop us if you saw this Web 2.0 name coming – Covr. Drawing its videos mostly from YouTube, it sorts them into categories including Christmas Covers, X Factor, Hit Song Covers, Music Genres, Instruments, Musical Covers, Disney, Game Covers and Anime Covers, according to TheNextWeb. Visitors can also search for specific keywords, and filter the results to avoid specific cover genres (for example ‘acoustic’ or ‘metal’). The videos are played full-screen in the browser with translucent interface elements hovering on top.
