The Fame era should've gone:
Just Dance (May 2008 - September 2008)
Poker Face (September 2008 - December 2008)
Eh, Eh (Nothing Else I Can Say) (December 2008 - March 2009)
LoveGame (March 2009 - June 2009)
Paparazzi (June 2009 - October 2009)
Boys Boys Boys (October 2009 - January 2010) (with semi-flirty music video like "LoveGame" that takes place at a stadium + bar, and ends in sexual assault)
The Fame (January 2010 - April 2010) (with a dark, satire-filled "Telephone"-esque video that parodies the tropes and ideas of Hollywood)
This is obviously if The Fame Monster never existed/was never released (the drastic change in attitude from The Fame to Born This Way would be made up by the darker themes of the "Paparazzi"/"Boys Boys Boys"/"The Fame" videos). It would've been interesting to see how the album would've done without The Fame Monster/the hype from "Bad Romance".
Btw, I was looking through pop radio archives, and I saw that "Eh, Eh" peaked at #87 on Pop Radio in June 2010, with 97 spins. I wish it was a full single in the US tbh, just to see how it would've done after "Poker Face".
"Dance In The Dark" peaked at 9 spins in July 2010, and I think "Speechless" peaked with 46 spins around the same time, so maybe it would've been a better choice for radio (although "Dance In The Dark" had the potential to be career defining tbh) . I'm not sure though and I can't check cause Pulse is down.
