Naive Player Questions

NO: a player does not "demand" an external file as my example stack 
demonstrates:

https://www.dropbox.com/s/9v2juqqu7ojb83v/Carrot%20Player.livecode.zip?dl=0

[ and I would be VERY interested to know, Graham, what that did to your 
DropBox ]

The player in that stack plays an embedded mp3 file.

Am I right to think the LC documentation is deficient in this area, or did I just miss it? For example, although it’s in the LC dictionary, “playstopped” can’t be found by searching the User Guide, which shows (IMHO) that users are not guided in any real sense about using players.

It all seems a bit of a mess to me.
