Exactly when was the last time we’ve witnessed a music battle this big? You can bet overly excited fans will be more involved in the waged war than the artists themselves. Let’s just hope we don’t see anyone making a video like THIS one. Nevertheless, things are certainly going to be entertaining this week as we see musical stars Rihanna, Lady Gaga, Shakira, Adam Lambert and Susan Boyle square off for the coveted number one slot on Billboard.

Let’s see how things are looking for the contenders:

Lady Gaga: She is still relatively new to the music community. The eccentric blonde bombshell has garnered more pop hits than any artist this year “Just Dance” “Poker Face “Love Game” “Papparazzi” and “Bad Romance” are all 10 top ten hits with 3 hitting #1. Lady Gaga’s unpredictable videos and performances have been praised by fans and critics alike. The sophomore release, The Fame Monster features 8 new catchy pop tunes-one being a guest appearance from Beyonce herself.

Rihanna: Thanks to her monstrous single “Umbrella”, Rhianna like Lady Gaga, has become a household name. The release of 2007′s “Good Girl Gone Bad” gave the world of music “Shut Up and Drive” “Please Don’t Stop The Music” “Take a Bow” and “Disturbia”. Now Little Miss Sunshine unleashes her fourth disc Rated R. The lyrically explicit albums enters more a darker territory for the “Russian Roulette” singer. Rihanna’s street hit “Hard” w/ Young Jeezy is one of the 13 tracks to make the cut.

Adam Lambert: Thanks to his risque performance at the 2009 American Music Awards Adam Lambert debut disc For Your Entertainment could possibly be his first number one. Earlier this year Lambert lost to Kris Allen, but despite being runner up to Allen, the flamboyant singer has been the talk of the town.

Susan Boyle: She’s the underdog in this competition. Susan Boyle story has won her over fans across the world. According to early predictions Susan’s I Dreamed A Dream could bow at #1, making her fairy tale story even sweeter. Could Boyle pull a upset victory over her competitors?

Shakira: She was a sexy She Wolf in her music video and did we forget to mention the very impressive bed choreography for “Did It Again”? Latin singer Shakira is no stranger to success as “Hips Don’t Lie” was one of the biggest Pop songs in recent history.
