there are soooo many options but it's gotta be this one, it's just so good and thematically it works really well, all the lyrics still make sense in the context of the 1920s.
this is a tough one. my answer will vary heavily depending on the genre and there are genuinely so many to cover from 2000 to 2009. however, if i was forced to listen to only one song on repeat, it'd probably be this one.
for some probably unlistenably messy, dissonant, and grungy but still i think its so fun and annoyingly catchy and really really good! - honestly a really funny thing for sonic youth to do at the peak of madonna's fame
