AceShowbiz - Ashley Tisdale finally makes her return to the music industry. After teasing fans for a few weeks, the former Disney darling unveiled her first single in nine years, "Voices in My Head", on Wednesday, November 7.

Produced by John Feldmann, the single revolves around her struggle to fight back insecurities that threaten her relationship. It finds her declaring her determination to break free from the insecurities and be happy with her partner. "All the voices in my head/ Always try to break me/ F**k me up and change me," she sings. "But talking is cheap/ This is the last time/ I listen to the voices in my head."

"Voices in My Head" serves as the lead single off her forthcoming album "Symptoms". The song was inspired by a slew of singles by other musicians such as "Ghost" by Halsey, "Don't Let Me Down" by The Chainsmokers and "Under Pressure" by Queen.

A music video for the song will be released soon.

Further details regarding "Symptoms" are still unknown. It will be a follow-up to her second studio album "Guilty Pleasure", which was released June 11, 2009. Generating mixed reviews from music critics, it debuted at No. 12 on Billboard 200 chart with 37,000 units. Despite its lackluster performance, "Guilty Pleasure" ranked seventh on Billboard's reader poll for album of the decade and best album of 2009.

Widely known for her role as Sharpay Evans in Disney's "High School Musical" franchise, Ashley began her music career in 2006, when she released her debut single "Be Good to Me". Her second single, "He Said She Said", was a commercial success despite mixed critical reception. It peaked at No. 21 on Hot Dance Club Play chart and was certified gold by the RIAA after selling 500,000 copies.
