One of America's longest-running reality shows is about to come to close. Fox announced on Monday that after 13 years on air, "American Idol" would be airing its fifteenth and final season in January 2016. While the series has discovered many musical stars we know and love today -- ranging from country darling Carrie Underwood to Oscar-winner Jennifer Hudson -- it has also introduced us to some of the worst singers in America. In honor of the show's long-standing reign, take a look back at eight of the worst auditions in the singing competition series' history. 

1.  Mary Roach

Mary, who had plans to change her name to Mary Guilbeaux upon reaching superstardom, delivered what was possibly one of the worst “American Idol” auditions. In Season 4, the aspiring singer and cosmetologist performed her rendition of “I Feel The Earth Move” by Carole King. Judge Simon Cowell broke the bad news, calling her “one of the worst” and “weirdest” voices he had ever heard.

“Are you just saying that to get on my nerves or are you totally serious? Because something tells me that you’re saying it to annoy me,” Mary responded.

The contestant went on to reveal that she has “a lot of voices” inside of her head and asked the judges if they wanted to hear her perform using one of them.

“The soundtrack to this section, I think, should be violin music,” Simon quipped.

2. Keith Beukalaer

Keith spent two months prepping for his “American Idol” audition by growing out his hair and dropping 15 lbs, but his looks didn’t earn him a golden ticket to Hollywood. In his audition, Keith belted out Madonna’s “Like a Virgin,” and even included a few dance moves into his performance. His audition left judge Randy Jackson in a fit of uncontrollable laughter and Simon visibly annoyed.

“Last year I described someone as being the worst singer in America. I think you’re possibly the worst singer in the world,” Simon said. “I’m absolutely serious. I’ve never, ever heard anything like that.”

3. Sarah Goldberg

After butchering Selena’s “Dreaming of You” during her Season 6 audition, the 20-year-old New Yorker admitted she was “tone deaf” not destined to be a singer.

“I’m not a singer. I really love to sing. I really do,” she told the judges. “Even I don’t sing, I can be the next American Idol. You want to know why? Because I’ve never sung before so you could teach me how to sing!”

After tearfully leaving the audition room, Sarah went on to rant in front of the camera, dishing about her relationships with the show’s security guard and the judges alleged drinking habits.

4. Jarrod Norrell

The aspiring singer came into into his Season 9 audition brimming with confidence, but his rendition of “Amazing Grace” failed to impress. After judge Kara DioGuardi compared his vocals to a “lawn mower,” Simon dismissed the contestant. Unfortunately for them, he didn’t leave the audition willingly.

“I’m tripping. I’m losing it. I’m just trying my best. Can I sing one more song?” he asked.

Despite denying his request for a second chance, he sang again. During his second performance he was escorted out of the audition room with two security officers. The cameras later showed him being handcuffed.

5. James Lewis

The contestant said his deep voice would bring something “new and different” to the “American Idol” competition and he wasn’t kidding. The then 22-year-old Philadelphia resident’s performance of “Go Down Moses” in Season 7 left Paula and Randy speechless.

While the judges told him singing was not his forte, James told the cameras he had plans to return to audition the following year.

6. Steven “Red” Thoen

Steven's audition had Paula jumping out of her seat, but not in a good way. His performance of Queen’s “Bohemian Rhapsody” on Season 6 was labeled by Simon as one of the “weirdest” he’s ever heard.

“It was like a 1 year old singing that song,” Simon said. “I’m not being harsh, that’s what it’s like.”

When the contestant told Simon to step up and coach him, he responded by saying, “It would be like coaching a one-legged man to winning a 100-meter sprint.”

7. Andrew Fenlon

In terms of his vocals, Andrew didn’t exactly blow his Season 9 audition, but his attitude towards the judges make him one of the worst auditions in the show’s history. Upon entering the room, the aspiring singer slammed Simon’s questions as “not that interesting,” later upsetting fellow Kara after revealing he was on edge from “waiting all day.”

“The thing is, you want to be on the music business but you don’t want to wait to get into 'American Idol,'” Kara said.

While Andrew tried to defend himself stating he was merely attempting to act “confident,” she did not let him off the hook.

“For you to have a bad attitude about that, kind of pisses me off,” she said, later accusing the signer of needing a “spanking.” Guest judge Victoria Beckham agreed, classifying the man as “even more arrogant than Simon.”

8. Isodora “Julie” Furman

Isodora classifed herself as a professional clairvoyant but it appears she was unable to predict the outcome of her Season 6 "American Idol" audition. After performing a very special rendition of "Lady Marmalade," Simon called her singing abilities "fantastically terrible." When Randy attempted to intervene and give the visibly upset contestant some advice, Simon said she wasn't worth their time.  

Season 15 of "American Idol" will premiere on Fox in January 2016. Jennifer Lopez, Harry Connick Jr., and Keith Urban will reportedly reprise their roles as judges. Season 14 episodes of "American Idol" air Tuesdays at 8 p.m. EDT on Fox.
