YouTube Playlist Tapes Accurate or Fake?

Hey. I have been unable to get them elsewhere since I only have a phone to carry around and for some reason my phone doesn't support the flac audio files. Even uploading the files to cloud storage doesn't work since it always results in weird distortions in the audio, repetitive glitches and weird cuts. These don't happen when I listen to the same file from my PC, only when I listen from my phone. Another storage platform I tried made it so that the binaural audio didn't work, and the voice/tones played the same in each ear. I'm not really a tech-savvy guy.

I'm struggling to troubleshoot this or find other means of getting the tapes. Currently the only ones that work are from a YouTube playlist I found. I think we all know which ones I'm talking about (blue background). Are those tapes alright to use? I've noticed that one of the tapes are 10 minutes shorter than they should be, and worry there might be other flaws that could spoil the experience. I know the first few tapes are ok to use, and are available for free from the Monroe Institute youtube channel, but I've surpassed those and I'm moving through them quite quickly. Need some feedback on this, thanks!
