The install file of xmms2-0.6DrMattDestruction-8 is unnecessarily verbose, even superfluous.

You don't have to edit it if you are running xmms2 as a user. This is much more convenient as the client automatically starts and stops the daemon. Even if you run the daemon as a separate user one usually knows where to look for the configuration of the rc script.

Since  FS#15575  all this -- now even outdated -- info is included in the optdepends array. Thus on package upgrade pacman prints it twice: once from the optdepends information and once from the install file. This is totally unnecessary.

In order not to clutter the pacman output with unnecessary output I suggest removing xmms2.install completely from the package. If a user needs more detailed info on the installation or the software the wiki is usually a better place for it.

I hope this does not sounds too harsh. I just want to keep the package clean. And thanks for taking care of xmms2. :)
