Hello. mathru.
Today I uploaded Dancing☆Samurai on YouTube.
Including that Dancing☆Samurai, from today you will be able to download mathru/Kanimiso-P's Vocaloid music as free !
Basically, you can download from note or booth.
Note is basically a song with songs, and Booth can download karaoke and thumbnail images including wav of the sound source.
※Please note that you may not be able to download some karaoke or thumbnail images due to rights issues or lost files.
Basically, you can use it freely, but there are restrictions for commercial use.
Please refer to the following page to confirm how to use it.
Please feel free to use it as a background music for videos uploaded to YouTube or niconico.
