Question: How many seasons was the singer of Someday a judge on American Idol?

full_context: Document 1: Someday (Mariah Carey song): "Someday" is a song by American singer and songwriter Mariah Carey from her self-titled debut studio album (1990). It is a dance-pop song with new jack swing influences. Prior to Carey signing a record contract, she and producer Ben Margulies had written and produced a four-track demo which included "Someday". After signing a contract with Columbia Records, Carey began work on her debut album and she reached out to Ric Wake to ask if he would produce the song, to which he agreed. The composition of the demo recording was changed during the recording process, most notably replacing the horns with a guitar, which Carey disapproved of.
Document 2: Music Box (Mariah Carey album): Music Box is the third studio album by American singer Mariah Carey. It was released by Columbia Records on August 31, 1993, in North America. The album comprises ballads primarily co-written by Carey and Walter Afanasieff, with whom she had previously worked on "Emotions" (1991), and a few urban dance tracks. During the course of the album's development, Carey wanted to broaden her audience, choosing a more pop/R&B oriented sound. During this time frame, she experimented with different musical instruments, leading the album's sound away from her more contemporary previous two efforts. Two unused tracks from the album sessions were released as B-sides: "Do You Think of Me" and "Everything Fades Away".
Document 3: Rainbow (Mariah Carey album): Rainbow is the seventh studio album by American singer and songwriter Mariah Carey. It was released on November 2, 1999, by Columbia Records. The album followed the same pattern as Carey's previous two albums, "Daydream" (1995) and "Butterfly" (1997), in which she began her transition into the urban market. "Rainbow" contains a mix of hip hop-influenced R&B jams, as well as a variety of slow ballads. On the album, Carey worked with David Foster and Diane Warren, who, as well as Jimmy Jam & Terry Lewis, replaced Walter Afanasieff, the main balladeer Carey worked with throughout the 90s. As a result of her separation from her husband, Tommy Mottola, Carey had more control over the musical style of this album, so she collaborated with several artists such as Jay-Z, Usher, and Snoop Dogg, as well as Missy Elliott, Joe, Da Brat, Master P, 98°, and Mystikal.
Document 4: American Idol: Much media attention on the season had been focused on the three black singers, Fantasia Barrino, LaToya London, and Jennifer Hudson, dubbed the Three Divas.

Elton John, who was one of the mentors that season, called the results of the votes "incredibly racist". The prolonged stays of John Stevens and Jasmine Trias in the finals, despite negative comments from the judges, had aroused resentment, so much so that John Stevens reportedly received a death threat, which he dismissed as a joke 'blown out of proportion'.

A fourth judge, radio DJ Stryker, was originally chosen but he dropped out citing "image concerns".

Additionally, "Emotions" features influences from a range of genres such as gospel, R&B, soul and 1950s, 1960s and 1970s balladry infusion. On the record, Carey worked with a variety of producers and writers, including Walter Afanasieff, the only hold over from her previous effort.

It is a socio-political conscious R&B-pop song which addresses the existence of poverty, racism and war in the world which gradually becomes more aspirational and positive as it progresses. The track garnered a mixed reception upon the album's release in 1990. While Carey's vocals were praised, it was seen as too political. An accompanying music video highlights social injustices. The song reached number 54 on the UK Singles Chart.
