First off, nice job on this project. It definitely spurred me on to give the songs/albums a more thorough listen.
The only thing that really stood out to me was that you called "Something" the best love song of all time. While I LOVE that song to death, I would never call it the best love song of all time. Perhaps it can enter in a discussion regarding the best expression of deep feelings for someone & the feeling of mystery and excitement that comes with not knowing what the future with them holds.
However,
I don't think it is best expressive of what 'love' is. Unfortunately, love's definition has become quite unclear due to the word's overuse & careless treatment.
I think the song that best expresses love -- done so in a beautifully poetic way -- is "Make You Feel My Love" by none other than Dylan himself. It is not as much about the emotions/feelings one may have for someone they love as "Something" is, but it definitely sings love in its purest & most sincere form.
Cheers.
