I classify Green Day as "whiny bitch music", it doesn't go into the same category as The love Pistols, The Ramones, or The Misfits.
The singer of the love Pistols is the whiny bitch who complains about Green Day being a punk rock band lol.
The Ramones is OG Punk, TSP is British Punk, The Misfits are horror punk. Green Day is just punk, with some songs being more pop-punk.
If you don't like them, then go be a "whiny bitch" about it somewhere else.
