Healing Music and Status Boost Music not available at rank 9

I just began making music scrolls, and I've created and tested multiple scrolls with +Strength, +Dexterity, +Will, and +Luck, as well as MP Recovery and HP Recovery. I've tested them solo, and in parties, and they never affect anyone. Every party has been tested with all members close together. My ranks are 9-9-9 for Playing, Composing and Knowledge.

I'm beginning to suspect that Rank 9 cannot play Magical Music, even the basic versions. This needs to be corrected on the wiki.

And my compositions last for well over 10 seconds.

No, rank 9 can play Magic Music, or at least it could about a year ago. Still, why would Nexon change it to a higher rank? It makes no sense. I did have trouble getting magic music to succeed while I was r9, but now that I am rank 5 I don't seem to have any issues.
