Ellie Greenwich, the New York songwriter behind a string of 1960s hits that gave effervescent voice to unbridled teen romance including "Da Doo Ron Ron," "Chapel of Love" and "Be My Baby," many of them in collaboration with producer Phil Spector, died Wednesday of a heart attack, according to her niece, Jessica Weiner.

"She was the greatest melody writer of all time," Brian Wilson [of the Beach Boys] told The Times on Wednesday. The chief creative force of the Beach Boys, whose music was strongly influenced by many of the hits Greenwich and her husband Jeff Barry wrote with Spector, has often cited "Be My Baby" as his favorite record of all time.

Their collaborations with Wall of Sound creator Spector are regarded among the greatest singles ever created. The music publishing rights organization Broadcast Music Inc. lists more than 200 songs she wrote or co-wrote, including "Then He Kissed Me" (the Crystals), "I Can Hear Music" (The Ronettes, Beach Boys), "Hanky Panky" (a hit for Tommy James & the Shondells), "Maybe I Know" (Lesley Gore) and the song Spector considered his greatest recording, "River Deep, Mountain High" (Ike and Tina Turner).
