Man! listen to the music YOU like. There's no strict rule about this! haha, my sybil is speedy enough for me, i've been practicing it for half a year now. I practice to the genre of music I like (which you should do too) I like Rap/Alternative/Anything with a nice beat (some rap doesn't but it helps relax me) But hey man seriously, do what YOU like best! Remember, this isn't meant to be strict, flourishing is meant to have FUN! Thats all you should worry about, and have fun with your sybil! =)
Cheers,
Eugene......SOH?!
