Dunno if this community is active at all...? But if it is, I'd love to request download links to the songs already made in Karafun.
In exchange, I bring a bunch of Hetalia karaoke songs! They're on Mediafire, should be downloadable from this link: http://tinyurl.com/y388wte
It's Marukaite Chikyuu in different version, Oishii Tomato no Uta, Oresama no Uta, Einsamkeit and other songs. Please use and share as you wish
