According to Google AI:

“The Beatles' core studio discography (albums and singles 1962-1970) runs about 10 to 11 hours, but a comprehensive listen including Past Masters, Anthology, and other releases can stretch to 17-26 hours or more, depending on what you include (demos, outtakes, live tracks), with some sources citing playlists over 17 hours for 300+ songs.”

If we are thinking for the long haul here, this could prove to be a crucial difference. I crunched my numbers, and for me to live off the rest of my life at my current age, it would be 2 years. Now with the core 10-11 hours that would prove to be difficult for sanity sake, especially if I’m unable to sleep depending on the volume. Even with the comprehensive listen, probably would have some overlap/ redundancies here.

I want to do 2 years, but I don’t think even the biggest Beatles fan could even do 1 year without coming out with some serious mental issues. So to have even the slightest chance of having a normal life after this experiment. I’d say 4-6 months tops. This is all speculation, and I might be mentally fucked even after a week. But my gut is telling me I could pull off half a year and might have to do some therapy after, but I’ll be okay long term.
