I am a fanatical Vim user who listens to iTunes frequently while working. But I don't see the point of this.

It takes very little time for me to switch spaces and click to change playlists, and I only need to do that a few times per day. Why clutter my Vim config with another plugin? Why claim valuable key bindings, both in my config and in my brain, for something I can already do well enough?

I'm not trying to be overly critical; if you like this, use it. But to me it feels like "let's order pizza from Vim!" or "let's compose symphonies in Vim!"
