_gracenote is a community of some classical music icons and other things.
The Rules for Use are:
1. You should put something along the lines of <b>taken from _gracenote</b> in the <i>comments</i> box in your userpics section if you are taking an icon. I prefer a credit to <b>_gracenote</b> rather than my normal journal.
2. Leave a comment at the entry taken from.
3. Share them if you want, as long as a credit is given in the userpic comments
