I dont know why, but at 40-50 min Youtube dropped a really anoying Ad that lasted over 15 seconds and let me lose my focus
UGH! Sorry about that. I do tell YouTube to NOT play any ads in the middle, but ... ultimately they do what they want. An option is I’m currently offering the Focus and Study pack for “pay what you want” pricing if you’d like to listen directly from your device without any ads: https://bit.ly/focus-study-binaural
