I love what the Beatles represent and acknowledge fully they were a cultural revolution basically and I admire all of them and if I had a choice of meeting Paul McCartney or Jerry Seinfeld, I'd choose McCartney without hesitation.
*That* said, I was born after the Beatles broke up so I don't really have as much of a nostalgic tie to their music as it was coming out. They have some beautiful songs, some of their songs are genius, don't get me wrong, but it's not like my favorite genre of music.
I pick Seinfeld. I grew up with that show, and it would help pass time better (several hundred episodes at 22 minutes each is way larger than the Beatles catalog).
And it probably would help you from going to loopy ala Tom Hanks in Castaway, watching people have conversations which is Seinfeld's speciality basically. Don't want to end up talking to a volleyball after 2-3 years. And it'd provide levity and humor.
