Deleted previous guide, please read below. I am not marking spoilers as they are to be expected. You can check your tapes collected in the ARCHIVE (settings menu, not the in-game inventory menu). They are based only on the current save-file and are not cross-save.
You MAY need to start from a new save, or a save BEFORE visiting the Gett Family Homestead AND Denver. I started from a save where i was only upto colorado springs, takes about 4-5 hours from there for all tapes if you rush it.
Playlist I created of some, but not all tapes (I ordered them A-Z).

Two tapes are choice related:
1. Kill Faran Brygo
at Little Vegas. It will be on his body. You MUST chose to attack him twice, DO NOT arrest him or you will need to reload / start a new game.
2. Chose to SAVE the Hoon Homestead in the Heads or Tails mission (the first mission you get when you are in the Kodiak), the tape is located inside the house.
The two tapes that have been fixed, they are missable but not choice related.Gett Family Homestead:
Speak to Grant in The Bizarre (east of the noodle bar) and offer to help him with the kidnapper problem. Leave & head back to the wasteland in the kodiak, head north & the homestead is right there. Upon opening the locked door (Lockpicking 7, or blow the door down) & it's on the body at the door.Denver, Machine Commune:
Inside the main structure, past the radio host - make a right & head towards Vivisecto - the "Robot Doctor" & it is located in the container just west of him.
