*1: About Sabi Medley
- This service is made possible by receiving information on the chorus from Songle (https://songle.jp/), an active music appreciation service developed and made available by the Media Interaction Research Group of the National Institute of Advanced Industrial Science and Technology (AIST).
- The position of the chorus played by Vocacolle is automatically analyzed by Songle's music understanding technology. If it is incorrect, it can be edited/corrected from Songle.
- Video contributors can fix the correct chorus position in Songle (you need to login to Songle with your Nico Nico account)
- The idea of "playback chorus one after another" is inspired by Songrium's "Super History Player (http://doc.songrium.jp/chorekishi/)" and "Smart Player (https://smart.songrium.jp/)" functions.

2: About CoverMIX
- This is made possible by AIST's derivative work recommendation technology based on information on derivative works provided by Songrium (https://songrium.jp/), a music listening support service developed and released by AIST.
- The idea of "playback so that it sounds like a single song" was inspired by Songrium's "relay playback" function.

3: Automatic playback recommendations
- AIST's music recommendation technology analyzes the acoustic signals of music content and plays content suitable for continuous playback, taking into account the similarity of musical tones and other factors.
