- ANIMEX 1200 (1300, special) series
ANIMEX 1200 is really a CD series, each volume is also numbered, and the Animex 1200 NNN is also reported on the sides and on the disc label. Moreover each Animex 1200 has a new mastering respect the previous releases. I think is a good idea to show the series and the number in the title.
- Columbia Sound Treasure Series.
As the name says also the "Columbia Sound Treasure Series" is a Series. It recurs on each Columbia page and subpage:
https://columbia.jp/soundtreasure/ and is indicated in each CD obi.
Show the name series in the title can be also good to immediately focus on what one is dealing with.
