It is indeed a very pretty song. I am not an expert on Beatles songs by any means but I do know some of their songs very well.
When I explore any band from the past - a band that I am not very familiar with - the main problem I encounter is that, I can't determine right away which songs are really great. For example, when you listen to any band's greatest hits, you run the risk of missing out truly great songs since they were not very mainstream; therefore, they weren't part of commercial success. The greatest hits or top 10 hits are usually a combination of their most commercially successful songs.
And that means I have to listen to all their songs and not just one time but many times to decide whether I really like the songs or not. I can't instantly dislike a song especially by great bands because a lot of the times, they tend to grow on me and later, I am so shocked to find out how good the songs are. Just don't want to miss out a really great song. I am so into music. It's basically food for my soul!
