Winamp had much better skins than Spotify, and great visualizations (which seem to have disappeared as a feature in the modern audio world). But Spotify does make it convenient to have a portable library that doesn't need backing up. I hate the lock in (unable to export playlists), I hate the inflexibility of their apps, and I hate that they can exercise both financial and editorial control over music and podcasts. Things are going in a direction where I'll ultimately miss Winamp and the 'old days of Internet freedom'. But the problem is that right now, Spotify is convenient-enough that we will continue the march away from the free Internet. We will keep marching until we hate Spotify, but there's little to stop us along the way until it is too late.
