The originally renewed twelfth season of the show was replaced by the third generation of the trilogy, which was revealed to be Battle of Songs.

Reception
The "Ex-Music" trilogy has been a trend for discovering varieties of songs. Throughout the trilogy, nearly 4,000 songs have been judged so far as of August 2021. Several notable songs that have previously appeared on their respective shows have been used for several specific purposes.

In early days, notable songs from there were featured for several special events ranging from its parent show, Music Factory, to its eventual successor, Music Station. Since Music Station took over the trilogy, notable songs have been mainly featured as background music for the distributor's fellow show, Spectacular SASUKE, although sometimes it has been performed for some events of Music Factory, which it might not likely to be held frequently due to the COVID-19 pandemic.
