Please consider updating the GPL-2.0 license text

[musicinmybrain]

The file LICENSE contains an incorrect/obsolete FSF mailing address. This is not a major issue, but it is easy to correct. Please consider using the latest GPL-2.0 license text from https://www.gnu.org/licenses/old-licenses/gpl-2.0.txt instead.

(The newer text refers to the GNU Lesser General Public License instead of the GNU Library General Public License, and there were trivial changes to whitespace and to placeholder text, but the terms remain unchanged.)
