Both Taiko no Tatsujin Session de Dodon ga Don (PS4) and Nintendo Switch Version are getting the same song as DLC on September 5 2019, by the price of 150 yen plus tax:
PS4/NS DLC Song: September 5 2019
| Title |  |  |  |  |  | |
|---|---|---|---|---|---|---|
 | Hypnosis Mic -Division Battle Anthem- ヒプノシスマイク -Division Battle Anthem-／Division All Stars | ★? | ★? | ★? | ★? |
The song is for the eponymous rap production multimedia project originating from 2017 featuring 12 male rappers divoded into four locality divisions. Currently there is no further pretense story from the other side.
As additionally noted by the official Taiko no Tatsujin Twitter feed, the full version of the song will be used; guess it is hard to cut up the song when most of it is solo portions for each of the 12 rappers. That makes the 5.5-minute song the new longest playable song in Taiko no Tatsujin ever. Whether it will break more "Taiko Guiness" records (like highest notecounts etc.) is unknown until actual release.
