I've never played a character with meditate skill so I have no idea how it
actually works. Now that we have it, are we supposed to click on the
Meditate button on the spellbook right after we start memorizing a new song
or does it kick in automatically?

I'm not going to be able to play again until the weekend so would appreciate
someone providing some feedback on how this new skill helps us out in
combat. What I'm hoping is that we can now memorize songs fast enough to
where, if in the middle of a tough combat and you realize you don't have the
song memmed that is best suited for that particular combat, we can back out,
sit down (assuming we aren't getting attacked) , and memorize a new song
that is beneficial for that combat.
