Title: Staind
Content:  Staind  is an American rock band formed in Springfield, Massachusetts, in 1995. The original lineup consisted of lead vocalist and rhythm guitarist Aaron Lewis, lead guitarist Mike Mushok, bassist and backing vocalist Johnny April, and drummer Jon Wysocki. The lineup has been stable outside of the 2011 departure of Wysocki, who was replaced by Sal Giancarelli. Staind has recorded seven studio albums: Tormented (1996), Dysfunction (1999), Break the Cycle (2001), 14 Shades of Grey (2003), Chapter V (2005), The Illusion of Progress (2008), and Staind (2011). The band's activity became more sporadic after their self-titled release, with Lewis pursuing a solo country music career and Mushok subsequently joining the band Saint Asonia, but they have continued to tour on and off in the following years. In 2016, Lewis reiterated that the band had not broken up, and would possibly create another album, but that his then-current focus was on his solo career. The band reunited more permanently in 2019 for several shows, continuing with live appearances in 2020. Many of their singles have reached high positions on US rock and all-format charts as well, including "It's Been Awhile", "Fade", "Price to Play", "So Far Away", and "Right Here".

Title: Staind
Content:  The topics of Staind's lyrics cover issues of depression, relationships, death, addiction, finding one's self, betrayal, and Lewis' thoughts about becoming a father in the song "Zoe Jane" from 14 Shades of Grey, as well as reflecting on his upbringing in the song "The Corner" from The Illusion of Progress. Also from 14 Shades of Grey, the track titled "Layne" was written about Alice in Chains frontman Layne Staley in response to his death in 2002. The song is also about Staley's legacy and the effect his music had on the members of Staind, especially Aaron Lewis. Staind has been categorized as nu metal, alternative metal, heavy metal, hard rock,    and post-grunge. In 2001, Rolling Stone outlined the band's relationship to the nu metal label: "Staind got their first break in 1998 when [Fred] Durst signed the band 
Title: Staind (album)
Content:  The making of Staind was a stressful experience for the group. As lead singer Aaron Lewis stated, "By the end of the first month we weren't even recording in the same places anymore." A number of factors created some dissension within the group during recording. Despite the deadline on the album's completion approaching, with the album less than half finished, Lewis continued to do solo gigs to promote his solo album Town Line much to the other band members' discontent. In addition Lewis' working relationship with drummer Jon Wysocki broke down completely. Wysocki's departure from the group was announced on their website in May 2011. Many songs were released before the album's official release date. The lead single, "Not Again", was made available as a streaming video on the band's official website on July 12, 2011. It was released to radio stations on July 19, 2011.

Title: The Stains (Maine)
Content:  The Stains were an American punk band from Portland, Maine, United States, in the early 1980s, and were led by guitarist George Ripley and vocalist Dave Buxton, Beth Blood and Ira Nulton on bass as well as Joe Potter on drums. Lead guitarists in the studio and in live performance included Dave Morton, Steve Soma, Marc English, Gary Gogel, and Roger Miller. The Stains released a 7" EP on Gutterworst Records with the songs "Feel Guilty" and "Give Ireland Back To The Snakes" on one side, and "Sick Of Being Sick" and "Submission" on the other. A posthumous album was released on the same label in 1989, featuring 15 more songs recorded between 1979 and 1983. Ripley and Potter along with Beth Blood moved on to form a garage rock band called GHOST WALKS. The Portland Stains are often mistaken as being from Boston, perhaps because they moved to Boston in 1981, and possibly because of some confusion with Steve Stain; a Boston-area punk performance artist who often borrowed musicians from various Boston rock bands, to back him up when he was performing. Sometimes he billed his impromptu band as "The Stains".
