All I can say is, "Wow" what a diverse year in the world of music. With that stated, I thought we would take a look back at the 10 biggest songs of 2011.This list is based on the sales numbers of each single and ranked in order.

No matter if you loved or hated some of the songs in this list, from the past year, you could hardly get away from them. They invaded your ears with frequency and somehow tapped into your subconscious, stuck and became 'ear candy'. I don't know how many times I've been heard in the halls of the radio station humming "Moves Like Jagger."

Collaborations were a big thing this past year with three songs in the top 10 featuring at least two or more performers on a track.

As you look over the list, I will also be referencing chart positions which are from Billboard Magazine's Hot 100 Singles Chart.

As Casey Kasem used to say, "As the numbers get smaller, the hits get bigger." So, let's roll out the hits and 'count 'em down.'

    Adele - Someone Like You

    This is Adele's second track inside the top 10, making her the first female to have two songs inside a year end countdown since Lady Gaga, two years ago, with "Poker Face" and "Just Dance."

    It should be also noted that this is the first time in the 53-year history of the Billboard Hot 100 that a song went to number one with just a piano and vocals.

    This was also the first song to spend 5-weeks at number one in both the U.S. and UK at the same time, since Katy Perry in 2008 with 'I Kissed A Girl."

    Nicki Minaj - Super Bass

    This was Nicki's second top 10 hit. It stalled on the charts at #3 and stayed there for two weeks.

    This was also voted #2 on MTV's "Best Songs of 2011" list.

    Look for Nicki on the upcoming Madonna song, "Give Me All Your Love."

    Lady Gaga - Born This Way

    Her real name is Stefani Germanotta and although she want's you to think she was 'hatched,' Lady Gaga was actually born in Yonkers, New York.

    Gaga was just named the 'Richest Female Performer" of 2011 by Forbes Magazine.

    This was Mother Monster's third and longest running hit. It peaked at #1 on the charts for 6 weeks.

    Foster The People - Pumped Up Kicks

    This song is the biggest selling song by a duo or group that wasn't part of a collaboration. It spent eight weeks at #3. That's the longest run in that spot for a song that peaked at #3 since LL Cool J's "Hey Lover" in 1995-1996.

    Cee Lo Green - Forget You

    Were do I even begin with Cee Lo? If you love this song and want to buy a copy, make sure you get the 'single' version, instead of the album or you'll be in for a surprise. For radio airplay, Green had to change the first word in the title to 'Forget,' since the original title and lyrics were using a different word that begins with F.

    This is the year's best-selling song by a male solo artist. It's also the year's best-selling song that failed to reach #1. It stalled at #2 for four weeks. It also picked up a Grammy for Best Urban/Alternative Performance and was a finalist for Record and Song of the Year.

    Maroon 5 feat. Christina Aguilera

    This is a song that, when I hear it, it's stuck in my head for the rest of the day. With the success of NBC's "The Voice," judges Adam Levine of Maroon 5 and Christina Aguilera teamed up for this catchy pop tune.

    After being in radio for over 30-years, this embodies what pop radio is based on; a catchy beat, a repetitive chorus and just a little 'left of center' to be memorable.

    Pitbull feat. Ne-Yo, Afro Jack, Nayer - Give Me Everything

    When watching any awards shows this past year, it seemed that Pitbull was singing on everybody's records. I know that an exaggeration, but he was either cranking out his own hits or providing some 'rapping' on another performers' song.

    This was Pitbull's first #1 record and Ne-Yo's second.

    Katy Perry feat. Kanye West - E.T.

    Perry is the only artist with three songs in the top 20 for 2011. "Firework" is #15. "Last Friday Night (T.G.I.F.)" is #19.

    This marks the third time in the past four years that Perry has had a song in the year-end top five.

    "I Kissed A Girl" was the fourth best-seller of 2008. "California Gurls (featuring Snoop Dogg) was #1 for 2010.

    This song held down the top spot for five weeks. It was Perry's fifth #1; West's fourth.

    LMFAO - Party Rock Anthem

    The thing I find most interesting about this group is that two of them are related to Motown Records founder, Barry Gordy, Jr. Stefan "Redfoo" Gordy is his son and and Skyler "Sky Blu" Gordy is his grandson.

    My question is, 'Where was 'Rockwell' during all of this?

    Adele - Rolling In The Deep

    The #1 song of the year is from the #1 album of the year, "21." Adele set a record with her song, 'Rolling In The Deep,' by selling the most digital copies in a single calendar year.

    To find a song of this magnitude, you would have to go back to before digital downloads to Elton John's 1997 tribute to the late Princess Diana, 'Candle In The Wind'. If we look at just digital downloads, then we'd go back just two years to the Black Eyed Peas and 'Boom Boom Pow."
