It’s bad enough you have 128 kbps MP3s, but to call that "high quality", is an absolute insult to high quality music. There is really no excuse why you can’t supply at least 256 kbps MP3s. Or even 320 kbps MP3s. Or even FLAC. The PCs these days have at least 500 GB, and up to 5 TB storage.
Also, my PC is OK as well… it has a lot of RAM. 16.0 GB.
However, there’s a small problem:
Please note where it says 14.9/16.0 Gb (Although it’s going down slowly now, it’s still 91% as of this post)
EDIT:
Do you want better quality? Well, if worse comes to worst, you can always try your luck and put up a request at one of the dedicated Request forums (http://forums.ffshrine.org/forumdisplay.php?f=95).
