Iconfinder is a search engine for (you guessed it) icons. It’s a great source for graphic designers to get inspiration or even download icons for commercial use. A search for “music” yielded 12 pages of results, the first of which is displayed below.
The site’s functionality is fairly basic but does allow you to change the color behind the icons to see how they work on multiple backgrounds, filter by the type of license, and filter by size.
