Our Most Likely to Succeed superlative category is where we get to gush about artists that may not be mainstream (yet), but have the potential to become huge. So if you don't know about all of these amazingly talented singers, you will very soon! Here are our nominees for Most Likely to Succeed for this year's PopCrush Yearbook Celebrity Superlatives, so take notes!

First off is the bubbly YouTube sensation Becky G. She's only 16 and can spit rhymes better than most 20-somethings, so we can't wait to hear her upcoming, Dr. Luke-produced, debut album.

Then there's Nikki Williams, who not only has the pipes and gorgeous looks, but has the brains (she co-wrote Demi Lovato's Top 10 hit 'Heart Attack') and wit to be the next supa-star. We just can't wait to watch her career soar and then say "I told you so!"

We've also got 17-year-old Austin Mahone who is riding out the success of two crazy catchy singles -- ‘Say You’re Just a Friend’ and ‘Say Somethin’' -- and Disney Starlet Bridget Mendler, who broke through to the music scene last summer with 'Ready or Not.'

Indie-pop has been making a comeback in a big way, like with EDM duo Icona Pop and their pulsing Top 10 hit 'I Love It,' as well as fellow alt-popster Charli XCX, whose debut LP 'True Romance' is like a mix of MGMT and Madonna, if that even makes sense.

British girl group Little Mix -- who won the U.K. version of 'X Factor' -- are slowly blowing up, with their first U.S. mag cover and a sound that reminds us of the R&B sass and harmonies of '90s group En Vogue.

The U.S. edition of 'X Factor' also produced some potentially successful groups: Surfer-cool boy band Emblem3 as well as Fifth Harmony, five girls with booming voices who are currently working on their debut, but have slayed covers by Justin Timberlake and Taylor Swift.

Australian pop rock outfit 5 Seconds of Summer are bringing their Blink-182 sounding single 'Out of My Limit,' on tour with 1D, and Kid Ink is getting ready to drop his 'Almost Home' EP which features his Meek Mill and Wale-assisted single 'Bad A--.'

And last, but not least, is R&B crooner B Smyth. At age 18 he has the moves and vocals to not only be noticed, but be compared to Chris Brown!

So, who should be named Most Likely to Succeed? Be sure to vote once every hour. Poll closes when summer kicks off, on Friday, June 21 at 12PM ET.
