my immediate reaction is to have it just append when you hold the button down,

Hmmmm... that's funny. MY immediate reaction is just the opposite -- I would always want it to insert rather than append, because when the mood strikes me to re-order my playlist, I want it to happen now, not some indefinite time in the future when my current playlist has finished playing.

As you point out, best option is to bring up the sub-menu so we can choose. Even if the way you would choose is totally incorrect. (juuusst kidding...)
