What is Lady Gaga's most timeless song and most dated song?
From the top of my head I would say Bad Romance which I know is probably an overrated answer but the fact that a song that came out 16 years ago but still gives us chills only from listening the opening note really says a lot. At a time where electropop was the thing everyone was doing, this operatic sounding song came along and could not have been done by anyone else but Gaga and still be listened to over again to this day.
For dated song I would go with Starstruck. I know some of you love it and it holds a special place in my heart but even I have to admit that the production, melody and feature makes it sound very of its time, it definitely doesn't mean it's a bad song but sometimes I feel like her record label wanted her to have this specific song.
