Thanks, everyone, for the tips and links! Excellent resources!
Thanks, too, for the welcome!
I've got my studying cut out for me, that's for sure.

As for the ID3 tags- I've been using some freeware called 'SelfRenamer', but I'll certainly look into the apps recommended here.
Other tools I use frequently are FreeRip and Audacity. The very simple player I use on the home box is 1by1.
The work on the tags will follow a review of playlist strategies...
lots to do now.
I'll keep my eye peeled for updates regarding the buttons, thanks!
