OneRepublic "Marchin On" Waking Up
OneRepublic really surprised me this era, especially because even when the first single of their last album wasn't that great for me, after that they released 3 amazing singles and Marchin On was one of them. This song makes me feel good every time I listen it. I love the sound of the drums. This is their 3rd entry on this list.
B.o.B feat. Bruno Mars "Nothin' On You" B.o.B Presents: The Adventures of Bobby Ray
This song introduced me to these 2 talented artists B.o.B and Bruno Mars and it was the start of an amazing year for both of them. B.o.B's rap and Bruno's singing are a perfect match in this song, which by the way has several nominations for the Grammys including Record Of The Year. This is B.o.B's 3rd entry on this list.
Taylor Swift "Back To December" Speak Now
I like the way how she can tell stories with her songs and this is one of them. In "Back To December" Taylor Swift show us that she really is a great songwriter. This is my favorite song of her and it's already at #8 without even a video realeased yet. This song is her only entry on this list.
Eminem feat. Rihanna "Love The Way You Lie" Recovery
Eminem's rap and Rihanna's chorus really complemented each other in this collaboration. Both parts are really good and this song has become in one of my favorite songs by them. This is another rap/sung collaboration with many Grammy nominations for this year including Song & Record Of The Year. This is Eminem's 2nd entry on this list as a lead artist and 3rd overall.
Maroon 5 "Give A Little More" Hands All Over
I think I'm probably the only one who has this song in the top 10 but oh well. I love the funky sexy sound of Maroon 5 in "Give A Little More" the second single of their last album. It's a shame that this song didn't do anything for the album and it was so unnoticed because I thought it has some potential when I heard it for the first time. This is their 2nd entry on this list.
P!nk "Raise Your Glass" Greatest Hits... So Far!!!
With a song about underdogs P!nk is at #5 with the lead single of her Greatest Hits album. I really enjoy the song, it's catchy and fun and it hasn't got old for me since I listened for the first time. Another solid single by the awesome talented underdog of pop music P!nk. This is her only entry on this list.
Muse "Neutron Star Collision (Love Is Forever)" The Twilight Saga: Eclipse: Original Motion Picture Soundtrack
Some people say (including Muse fans) that this is Muse's worst single but I disagree with them because this song is really amazing. It's not their best but still it's a great work by them. I love the melody, the lyrics, the sound of Matt's powerful voice. Neutron Star Collision is a love song and it works perfect for what it is and I love it. This is their 3rd entry on this list.
Bruno Mars "Grenade" Doo-Wops & Hooligans
The multitalented Bruno Mars is at #3 with his last single "Grenade". This is one of those songs that caught my attention with the first listen and this didn't happen to me with his first single "Just The Way You Are" which was a grower for me. In fact I think I liked first "Grenade"and then I liked "Just The Way You Are" Anyways I'm glad that "Grenade" is already a huge single for Bruno Mars because the song is truly amazing. This is his 2nd entry as a lead artist and 4th overall.
Rihanna "Only Girl (In The World)" Loud
I don't know if it's too early to say this but "Only Girl" has become in my favorite Rihanna single ever, I just love it. And not only that but her last album is so amazing that I'm officially a fan of her. Before I was just a casual fan of some of her singles but with her last album everything changed. It has so many potential singles and it's so diverse that this year she probably will continue ruling the charts with whatever she wants to release. This is her 3rd entry as a lead artist and 5th overall.
Christina Aguilera "You Lost Me" Bionic
The #1 belongs to the haunting ballad "You Lost Me". Christina Aguilera gave us one of her best vocal performances on this song which sadly was so outshined for all the bad press surrounding her last album Bionic and its underperformance on the charts. When I heard the previews of the tracks of Bionic this was one of the songs that caught my attention immediately. Sia and Christina did a great work with this song, the melody and the lyrics are so beautiful and for me it's just as amazing as some of her classic ballads like "Beautiful", "The Voice Within" & "Hurt". This song deserved a much better video though. This is her 3rd entry on this list.
I agree what you say about "Neutron Star Collision", but it is also truth that it is a bit overrated. But well, this is what happens to every band that release a song for this kind of popular films. Anyway I like the song, actually it was #86 in my countdown.
I'm not a fan of that Christina's song, sorry, but the rest of the Top 10 is great, except for "Back To December" that I haven't heard.
But I like it overall, specially the rest of the top 5!
RECAP
but oh well. I love the funky sexy sound of Maroon 5 in "Give A Little More" the second single of their last album. It's a shame that this song didn't do anything for the album and it was so unnoticed because I thought it has some potential when I heard it for the first time.
Anyways I'm glad that "Grenade" is already a huge single for Bruno Mars because the song is truly amazing.
I also think it's one of the Muse's best and I hate how other people find it overrated just because its from Twilight 
It's the first song I ever played when I passed my final subject in college. Its so inspiring! 
Epic list.
