British teenagers like to watch their music online. Watching music on video streaming sites on the internet is now more popular than listening to the radio with young British people. Popular videos can quickly become extremely popular internationally. Justin Bieber’s song ‘Baby’ was the most watched music video on YouTube until 2012. Then, PSY’s ‘Gangnam Style’ became the first video to get a billion views. Now, it’s quite common for videos to pass the billion mark. Things can change quickly on YouTube!
