Since there is YouTube , why not have something like SoundTube or similar

We are all very aware and the impact of YouTube upon this culture of Millenials has not gone away from those that run YouTube. However much of that content has a visual component to it, that is not always in sync, or is totally silent. While there are services that are for audio streaming and HazzardAyre in on two of them, SoundCloud and Spreaker, still I'd like to see just a consumer/audiophile's version of YouTube that could be called something like SoundTube. No video only audio. Granted gaining the music treasures that are part of YouTube, might be a task, but a all music and or radio or both consumer site that is absolutely free at least to subscribe to and groove on, would be a concept that would make serious money. Sure there are subscription services like IHeart.com and Pandora but to catch the real tune grooves, you have to pony up at times serious cash out of your stash. 
How about a SoundTube? 
More on that on my show at 17:00 today, on : www.livestream.com/hazzardayrecoast2coastfm .
