I Want You (She's So Heavy)
Discussing Lennon's "I Want You (She's So Heavy)", "Guitar World"s Josh Hart and Damien Fanelli called the song a "bluesy rocker" that "might have inadvertently started doom metal". Jo Kendall of "Classic Rock" magazine similarly commented that the song predated "Black Sabbath's creation of doom rock by several months" and noted the "Santana-like Latin blues section" in the song. James Manning, of "Time Out London", describes the song as the foundation for stoner rock.
