Spotify has enabled fabulous and powerful music discovery experiences for me. For sure it's not perfect and there are many ways to discover music - I'm really glad that you and others are working on new ideas in this space. But I reckon it will be hard to compete with Spotify's algorithmic playlisting expertise and resources.

It would be nice if Spotify added some deeper playlisting functionality tools to give users a bit more control.

However, for me, algorithms are just tools and the best 'radio' will always come from DJs and other humans making mixes and music programs.
