I use a site called https://www.queup.net which is a successor to turntable.fm. You find a "room" with a genre of music you like and just sit back and listen to people DJ using soundcloud and youtube videos. I have it on all day in a room that is majority electronic/chill/lounge and mostly non-vocal. I've learned about so many artists this way but you need to find an active room you like, and sites like these tend to skew towards the many different electronic subgenres
