"S'y prendre" means having addresse to do something. It means that we use somes good or bad ways to succeed what we are doing. Like "Je m'y prends mal" (I do it wrong) it's the way you're doing this. And in "Je veux m'y prendre bien à l'avance" it's the person wants to do it right, like doing this long time before her birthday. So at last "se prendre à faire quelque chose" means you put more or less address in your action :) I don't know if you understood ? Because french use it often, but even for use it's haard to understand what it really means XD

You can also listen to "Juste Pour Me Souvenir" from Nolwen Leroy

I like "Chanson Sur Ma Drole de Vie" from the movie "Tout Ce Qui Brille" And the lyrics are good for understanding the accent.
