How do you do it?

[PyramidHead]

How do you keep up with all the songs you learn? Is there only a certain number of them you need to use? And how do you remember all of the effects of each song?

[bbcradical_ed]

only need to know a few...and from playing them for hours upon hours you get to know them quite well

[Vilurum]

Not that hard ... you get a gazillion actual songs but many of them are simply new versions of old songs. And once you get past the flurry of levels at low levels and levelling starts to slow down, you take more note of each new song you get when you level. But just as a simple breakdown:

Buffs:
Minne: defense
Minuet: attack and ranged attack
Paeon: HP regen
Ballad: MP regen
Madrigal: accuracy
Mambo: evasion
March: haste
Prelude: ranged accuracy
Etude: stat-up
Carol: elemental resistance

Debuffs:
Requiem: gradual damage over time
Elegy: slow
Threnody: decrease elemental resistance
Lullaby: sleep
Finale: dispel

Then there are a bunch of songs that you don't use much (like all the status resistance songs), and songs with unique effects such as Mazurka, Hymnus, or Virelai.
