This R&B song -- with auto-tune vocals and a synth back-beat -- is the first single from Taio Cruz's September-released album 'Rokstarr.' Originally penned for UK singer Cheryl Cole, this No. 1 UK hit has been remixed in 2010 for the US version that features rap sequences by Ludacris.
9) Jay-Z: 'Young Forever'
This Jan. 26-released single is the fifth song featured off his 2009 studio album 'The Blueprint 3.' Produced by Kanye West, this best song of 2010 features British R&B/pop singer Mr. Hudson singing splices of Alphaville's 1984 hit 'Forever Young' -- while Jay-Z raps original lyrics. You may remember the 1984 version from the prom scene of the cult classic 'Napoleon Dynamite.'
8) Taylor Swift: 'Today Was a Fairytale'
This is one of two tracks by Swift featured on the soundtrack for the forthcoming film 'Valentine's Day' (opening in theaters Feb. 12, 2010). Swift makes her onscreen debut, alongside a slew of actors, including heartthrob 'Twilight' actor (and possibly ex?) Taylor Lautner. The raw guitar sound and romantic lyrics will make any love-bound tween swoon: "But can you feel this magic in the air? / It must have been the way you kissed me / Fell in love when I saw you standing there."
7) Owl City: 'Vanilla Twilight'
A follow-up to 'Fireflies,' this love anthem is for those enduring a long-distance relationship. The single still has Adam Young's whimsical synth-pop, crescendoing from his piano solo as he sings: "I'll watch the night turn light blue / But it's not the same without you / Because it takes two to whisper quietly." Featured on the July-released 'Ocean Eyes,' the deluxe edition was released Jan. 26.
6) Kevin Rudolf: 'I Made It'
Featuring Cash Money collaborators Birdman, Lil Wayne and Brit R&B newcomer Jay Sean, the rock/pop song is about, well, living the dream and making it as an artist. Weezy adds notable punchlines in the bridge: "Made it to the goal line, straight out the huddle / Cash money goldmine, Weezy stay loyal / Boy we getting money like we just found oil." The song will be featured on Kevin Rudolf's forthcoming, still untitled, sophomore album.
5) Selena Gomez & the Scene: 'Naturally'
The second single off Gomez's September-released debut 'Kiss & Tell', the electropop tune premiered on 'Radio Disney.' Gomez sings about a boy who is a perfect fit for her: "When you know it's meant to be / Everything comes naturally, it comes naturally / When you're with me, baby."
4) Justin Bieber: 'Baby'
Featuring Ludacris, the song is no stranger to Beiber's formula: R&B beats and puppy love. Ludacris even raps about his first love: "She had me going crazy / Oh, I was star-struck / She woke me up daily / Don't need no Starbucks / She made my heart pound." This best song of 2010 is featured on his forthcoming album 'My World (Part II)' debuting this spring.
3) Lady Antebellum: 'Need You Now (2010 Mix)' (My Personal Favourite)
This top song is about the longing of late-night companionship. A beautiful ballad for a booty-call, the song reached No. 1 on the Hot Country charts in November, eventually transitioning over to pop radio as well as the Billboard 100. Just last week they pulled a Taylor Swift and released a 2010 pop mix version -- electric guitar replacing the country guitar twang in the chorus and the bridge. Subtle, but it does the trick.
2) Ke$ha: 'Blah Blah Blah'
Featuring the playful rap duo 3OH!3, Ke$ha sings (over video game-sounding synth beats) about getting with a guy. Blunt and emotionally removed, the clean version still gets the point across, minus some of the verbiage in this unrefined line: "I don't care where you live at, just turn around boy and let me hit that / Don't be a little b-- with your chit chat, just show me where your d-- at." This best song of 2010 is the second released-single off her debut album 'Animal.'
1) Lady GaGa: 'Telephone'
Not to be confused with Beyonce's remix of 'Video Phone' -- which also includes Lady GaGa -- this top pop song is featured on GaGa's 'The Fame Monster' and was released as a single on Jan. 26. Although the song incorporates a harp, it's definitely club-ready -- and features a surprising rap sequence in the middle by Beyonce. Written by GaGa and Rodney "Darkchild" Jerkins, the song was originally intended for Britney.
