Everybody has his/her opinion, for instance My favourite Abbey Road songs are:
1. Here Comes The Sun
2. I Want You (She's so Heavy)
3. Golden Slumbers
4. The End
5. Come Together
6. Something

I love heavy John Lennon, and for me there's nothing heavier in AR than I Want you, a hipnotic riff, Lennon's raw vocals and screaming similar to his Plastic Ono Band Album, great drums by Ringo and bass by Paul. A have a friend musician and music teacher, very talented and picky about music and he always says that the most interesting track for him (musically) in the album are IWYSSH and The End next.

I've seen so very cool versions of this track, here's one of my favourites by this girl I saw the other day in youtube
