The group's song about the late singer will feature on the second of their three-album series, ¡Dos!, which they revealed deals with "the consequences of the party".
Billie Joe Armstrong told NME: "I didn't know her, I just thought it was a real tragic loss.
"It's interesting because if you think about ¡Dos!, it's a party record and so at the end of it maybe 'Amy' kind of comes across as the consequences of the party.''
Discussing Winehouse's legacy, Armstrong continued: ''I just thought her music and her taste in music was so connected to old soul music and the original Motown and Otis Redding and Sam Cooke and things like that.
''I think that was a major loss because that was a generation's connection to that, and this was someone who should be here now and I just felt really sad."
Green Day recently debuted the first single from their album trilogy 'Oh Love', which is out in the UK on September 24 and a day later in the US.
