The new website where you can download alternative music fonts is now live! Head on over to fonts.openlilylib.org and try them out! If there are any broken links, please let me know so I can fix them. If any instructions are unclear, please let me know so I can clarify them.
Just a heads-up: You must have at least the LilyPond 2.18.2 in order to use the new fonts. Starting with 2.19.12, this functionality is built-in. Between the two, you will need to manually patch LilyPond, which isn't hard to do. All the instructions are found for both situations are found on the website.
