Poker Face & Just Dance made 2009 in America (by which stage Eh Eh & Love Game were slaying in Australia, the US were so late to the party tbh).
3 is not forgettable. People sing it all the time without realizing, not because they love the song, because the chorus is so damn catchy it's annoying.
Fireflies is not forgotten, MESS. It's one of the only #1's from 2009 to actually become a classic track that everyone knows.
3 is probably one of Britney's most forgettable songs, I can barely remember the chorus. CAB though takes the cake, I don't even have a vague memory of the beat
1, 2, 3 / Peter, Paul, and Mary / Getting down on 3P / Everybody loves me
So crack a bottle / Let your body waddle / Don't act like a snobby model / You just hit the lotto
It's horrifying how I still remember these songs.
I voted for Crack A Bottle even though I have heard and still remember it.
