I feel for you, Ally. Discord is quite a pain to raise. Baldguy made some excellent suggestions if you don't want to waste your 15 music points.
It just goes back to what I mentioned in the OP. Your success chance is based on your music, discord (or provoke or peace), and the instrument you are using. Since you have 115 Music, it makes it easier for you to succeed, therefore harder to gain. So really, if you practice on things with higher difficulty, then your 115 Music isn't a problem. I suggest you use the barding calculator on Stratics. Just plug in your skills and it will give you success rates for any monster you pick. You want your success rate to be somewhere between 40% and 60%. 115 Music may make it harder for you to gain at higher levels, but if you just adjust and train on the right creatures (my list probably isn't very accurate for you) then you'll gain normally, which is still too freaking slow.
