The big trouble with Blow is that it sounds like TTWE's special cousin not to mention like everything else on radio at that time. All those songs will be forgettable with the exception of a couple that manage to stand out (TTWE). Blow did not.

Of the #1s:
Black and Yellow
Hold It Against Me
Grenade

Of the rest:
Friday
The Lazy Song
On The Floor

Where's ''Hold It Against Me'' on iTunes?

I didn't find it http://ax.phobos.apple.com.edgesuite...imit=0/rss.xml

For having a different opinion than you?

LEAVE BRITSTEP ALONE!!

Any Pitbull song

Holy ****! It's not there!!!

Um, no. The flamebait is going too far.

What Tha Hell...Oh wait

Blow sounds NOTHING like TTWE

purposely leaving out your fave in your list but adding every single other smash

btw isn't forgettable just because it didn't live up to the hype
even your paraplegic grandmother knows the chorus

I still dislike that song.

Of the #1s

S&M(Remix)
Black & Yellow
Maybe "Last Friday Night"
Party Rock Anthem(although Wiki says it lasted as long as BTW)
and HIAM

Give Me Everything, Party Rock Anthem, Black & Yellow

Last Friday Night.

I seriously do not understand why so many people are bringing up Born This Way.
Sure, it may not be anywhere near you top twenty songs of the year, and you may hate it, but it is certainly not forgettable.
In fact, I would argue that out of all the smashes this year, Born This Way had one of the biggest cultural impacts out of all of them.

From the number 1 hits this year, Black and Yellow, S&M (unfortunately), and LFN are the most forgettable smashes of the year.

Blow is eventualy outselling BTW

Born This Way
Moves Like Jagger
Party Rock Anthemn
