davexnet, it kind of sounds like you're going out of your way, entering your 'minimal' Linux install, to play and share Music when; you have two Win OS's from which it seems more logical to play your Music ?
It's good to install PCLinuxOS in any form, just to play around however, it is always a learning experience, please don't take me the wrong way. Whatever you do has its advantages, and disadvantages, and I think µT6, and Just17 have covered your options. My main concern seems to be 'Space.'
Without knowing
how large the Linux partition is, and how much Media you intend to place there, it's hard to know what to recommend. Suppose personally I wouldn't store 'Music' on a little Linux partitition, rather
leaving breathing space for System Updates; storing Music, Media, etc., on a larger Volume. Just my two cents.
Have fun any how !

I set up PCLOS on an existing Windows PC and I did the most basic
Linux install, two partitions, one swap partition and another for the OS and all the home locations.
