Hi, I am the current maintainer of osd-lyrics (http://aur.archlinux.org/packages.php?ID=30489). One of the upstream developer commented on the package and requested a rename to osdlyrics, and I have uploaded osdlyrics (https://aur.archlinux.org/packages.php?ID=50877) accordingly to AUR. Although upstream page on googlecode is still osd-lyrics, their github name is osdlyrics. and I have found a git commit explicitly convert all osd-lyrics occurrences into osdlyrics. So, osdlyrics should be the upstream choice for the package's name. Sorry for all the mess this package has created.
Best Regards,
