Tyler Hayes posits another argument for YouTube music:
Is there an etiquette for sharing music? A link to any of the music services, even the most popular ones, will inevitably fall on a few deaf ears of people you’re trying to reach. Not for lack of interest in the music, but rather in having to use a specific service. Since it’s 2013, you can’t just listen to music anymore, you need to be tied into an ecosystem. So, what’s the right way to share music, and actually get the other person to click through and listen?
