Concept wise. I wish people would stop trying to push the user voted content model onto music. Or any kind of art for that matter.

Community voted stuff works great where the end result is common across the entire userbase. Everyone wants to stay up to date with the latest news articles or funny youtube videos. This is why Hacker News and Reddit work well.

The fact is though that my idea of what makes good music is going to differ hugely from the next person. The top submissions are simply going to be the least offensive, most agreeable. I think soundcloud realise this which is why thier explore tab picks randomly.

I agree with the ideology of sharing music and making it easier to access, but it's something way too subjective to apply this approach to. If all music was ranked by popularity, we would end up with something called a chart, and ironically "chart music" was probably a huge driving force for you to branch out and explore music that connected with you as an individual.
