Hi, I recently downloaded the N H K Ni Youkosou OST, I wanted it mostly for one main song, for the people who have seen it might recognize it, it´s a guitar with drums song, however the OST includes it but with vocals, it´s called Youkoso! Hitoribocchi by Pearl Kyoudai, does anybody know if there is any instrumental version of it ? the vocals are a bit annoying on it. thanks
