Thanks for all the comments!
020. Foster The People - Pumped Up Kicks
I remember thinking this was such a fun and care free song until I read the lyrics and found out what I really was about. You certainly don't expect that while listening to the song without really listening to the lyrics. It's just a very good song and one of the biggest surprise hits of the year for me. Love the video aswell. Simple but so effective.
019. The Saturdays - Notorious
The Saturdays went for a dancier sound with the release of this song. While it wasn't the big hit most of us fans were hoping, I still think the song itself is brilliant. It's so catchy and Mollie singing that 'she's a gangsta' is just the cutest thing ever

The girls did some great live performances for this aswell and I just couldn't stop singing the lyrics during the summer. Although it is a bit weird when I sing some of them ofcourse.
018. Nicki Minaj - Super Bass
Nicki already did pretty well in the UK, but it wasn't until this song that she scored a massive hit. I can totally see why, it's just so unbelievably catchy! It's a lot more pop than most of her songs, but I think she does this so well. The video reminded me a lot of a 2011 version of California Gurls, so bright and colourful.
017. Emeli Sandé - Heaven
Emeli is for me definitely one of the most exciting new artists. Heaven was her first solo single and became a big hit for her. I didn't like it at first, but I remember Fearne playing it on Radio 1 and I just fell in love with it. Such a good song and she is an amazing vocalist. I saw her live last month and she is just phenomenal.
016. Tinie Tempah featuring Kelly Rowland - Invincible
Invincible is one of the highlights on Tinie's brilliant debut album. While the song did pretty well, I think most people have already forgotten about it. Like with Jessie's What Laughing Now, it feels more like a release between two obvious singles. But I think this is such a gorgeous song, much better than Wonderman for example. Tinie is on top form and Kelly sounds so beautiful aswell. The perfect combination for this song. ADORE the video aswell.
015. Lady GaGa - Judas
I absolutely hated this when I heard it for the first time. I was thinking to myself, what is the doing!? As this was actually the first Lady GaGa song I didn't like. It changed pretty fast after that and I now think this is so good. Her voice sounds so moody on it, that's what I love. The 'bring them down, down down' parts are my favourite. The video is definitely the best one of this era and I have to say how beautiful she looks in it.
It did pretty bad everywhere though, especially for a big name like her but it's so catchy. One of the highlights on the very disappointing album.
014. Rihanna - S&M
This song is just teh sex and who better to sing it than RiRi? She doesn't take herself too seriously, which she showed with the video and I love her for that. Incredibly catchy, filthy lyrics (and a horrendous Radio 1 edit) and literally everyone was sining this song. I know it's not a popular opinion, but I like the Britney version a lot aswell. Britney sounds so sexy on it.
013. Lady GaGa - Born This Way
This song has been in my top 10 all year and it literally dropped out while posting this update. I realised there are a couple of songs I love more now. This also means that it's Lady GaGa's final entry and it's the first time since I charted her back in 2008 to completely miss the top 10.
This doesn't mean that I don't love this, I still do. It's a great pop song with some very inspirational lyrics. It's still the biggest selling single this era, mostly because of it's insane opening week everywere, and for me personally the best.
012. Jennifer Lopez featuring Pitbull - On The Floor
I don't think anyone could have predicted around this time last year that Jennifer would come back with one of the biggest singles of the year. But she did and proved everyone wrong. Together with Pitbull she stormed the charts with this party track. You just want to stand up and dance when you hear this song. And with the promotional performances she did of this song, she showed once again that she still is one of the best performers out there.
011. Olly Murs - Dance With Me Tonight
And Olly's most recent single just misses the top 10 with an entry at #11 here.
I don't even know where to begin with this song. The opening lines of 'My name is Olly' which I love, the dance moves, the cheeky lyrics which he is known for. This track has such a retro feeling and is still so modern at the same time.
The video is great aswell although the X Factor performance with The Muppets was a little bit random.
