docs: rephrasing suggestion

[thomas-mc-work]

Based on this statement:

mpc/doc/index.rst

Line 168 in 6e248c4

:command:`next` - Starts playing next song on queue.

Wouldn't it be better to phrase it "Continues playing next song on queue.", since it won't start playback but only continue. When I call next in a paused state I get: MPD error: Not playing.

"Continues" is just as ambiguous, because you can't continue something you have never started.
Maybe "Skip to the next song" would be better than that?

[thomas-mc-work]

you can't continue something you have never started

Isn't that the point of the statement? Keep on going if you are going already. Fail if you're not.
