Clear Music Cache on Extender

[aeblank]

I have MC7 and two extenders. I mucked with my music library (removed almost everything) and I cannot get the cache to clear on the extender.
I know there is a folder to delete in the ehome folder for the main user. i also deleted it for one extender, and the other extender doesn't have that folder.
MC and one extender show the library correctly, and the other extender shows the old library (not sure which extender had the folder and which didn't).

So, how can I clear the music cache?
Can I automate it or have it do it every so often? I want it to act more like the "videos" folder with more dynamic (smarter) updates.

Thoughts?

Reboot both?

Dissociate extender, and then associate again?

I reboot now and then. Guess it's disassociate, but was hoping to not have to. Wanted something i could automate.
