These are songs from other anime series composed by Shiro Sagisu that more than likely won't appear in the official release of the Bleach Thousand-Year Blood War OST, despite being played in the show.  "14. dyna tension and pinch" from SSSS.DYNAZENON - Played at Episode 01 when Ichigo fought Asguiaro Ebern, and Episode 10 when Ichigo and Renji were fighting the Asauchi. "16 - Infiltrators" from BERSERK (2016) - Played at the end of Episode 14, and during first half of Episode 23 (Mayuri vs Zombie Toshiro). Edit: Looks like "dyna tension and pinch" WILL be in the official OST. It's the 4th song. Listen to the preview here: https://www.youtube.com/watch?v=z9sOfrxjAvg
