For example, the axeso5 version of "Audition Online" has to name all their new songs - Month Year - Song no. (e.g. Febrero 2015 - Tema 04) while listing on their website the actual music title and artist it is by. Users can then find the title song by Tema 01, Tema 02, etc. While particular people in the game have pointed out that this method is used by axeso5 probably trying to avoid copyright claims whilst still adding more popular songs, their claim still remains a speculation and has not been proven.
