hmm... well i was thinking about this, and i think that you have to kinda classify who and what OUR generation is. Like... me and you jp... we arent that different in age, but i think my generation is like.... Bush, Pearl Jam, kinda skater grunge rock...
So THAT generation I would consider Nirvana : Smells Like a Teen Spirit would be something that defined that generation.
Maybe late 90's turned into a mish mosh of stuff...
Plus, defining a generation would also have to take into consideration where they are from, backgrounds and such. Like... some other people may have other suggestions like Superhero said, Hiphop or Metal, ya know?
But yeah... personally Nirvana has my vote.
well thats true. for my generation, personally, id have to say maybe basketcase by green day or a blink 182 song. thats very defining of the poppunk era, at least that stuff got me into music a lot. but i kind of mean more like the song that defines the mid-2000's. like what will be remembered. i think its mr. brightside because of the whole indie rock movement that surrounded it. it popularized indie, or helped too. i thoguht of this especially last month when i went to two parties in one weekend, and each time, even though you dont usually hear non-dance/hip hop whatever at the parties, both times, mr. brightside was played, and all the kids loved it and were into it more than anything else. its a good song.
