Listening to music is one of the regular activities that most people do on web. There are plenty of web services, smart phone apps to deliver some good quality free music out there which are being used by most people daily. The popular services like YouTube, SoundCloud help people to discover new and their favorite music easily.
For millions of internet users around the world, YouTube is their completely free music streaming service. But if you've ever tried using YouTube that way, you know that the experience is far from optimal. The biggest deal breaker for me is that there's no queue. And YouTube's playlist feature is way too basic.
