   If you're the original submitter of this issue, please comment confirming if this issue still affects you in the latest release or nightlies, or close the issue if it has been fixed. If you're another user also affected by this bug, please comment confirming so. Either action will remove the stale label.
 
   This bot exists to prevent issues from becoming stale and forgotten. Jellyfin is always moving forward, and bugs are often fixed as side effects of other changes. We therefore ask that bug report authors remain vigilant about their issues to ensure they are closed if fixed, or re-confirmed - perhaps with fresh logs or reproduction examples - regularly. If you have any questions you can reach us on [Matrix or Social Media](https://docs.jellyfin.org/general/getting-help.html).

+  <plot>Dancing Queen est un des tubes emblématiques de l&apos;ère disco produits par le groupe suédois ABBA en 1976. Ce tube connaît un regain de popularité en 1994 lors de la sortie de Priscilla, folle du désert, et fait « presque » partie de la distribution du film Muriel.&#x0A;Le groupe a également enregistré une version espagnole de ce titre, La reina del baile, pour le marché d&apos;Amérique latine. On peut retrouver ces versions en espagnol des succès de ABBA sur l&apos;abum Oro. Le 18 juin 1976, ABBA a interprété cette chanson lors d&apos;un spectacle télévisé organisé en l&apos;honneur du roi Charles XVI Gustave de Suède, qui venait de se marier. Le titre sera repris en 2011 par Glee dans la saison 2, épisode 20.</plot>

+    <review>The Best of 1980-1990 is the first greatest hits compilation by Irish rock band U2, released in November 1998. It mostly contains the group&apos;s hit singles from the eighties but also mixes in some live staples as well as one new recording, Sweetest Thing. In April 1999, a companion video (featuring music videos and live footage) was released. The album was followed by another compilation, The Best of 1990-2000, in 2002.&#x0A;A limited edition version containing a special B-sides disc was released on the same date as the single-disc version. At the time of release, the official word was that the 2-disc album would be available the first week the album went on sale, then pulled from the stores. While this threat never materialized, it did result in the 2-disc version being in very high demand. Both versions charted in the Billboard 200.&#x0A;The boy on the cover is Peter Rowan, brother of Bono&apos;s friend Guggi (real name Derek Rowan) of the Virgin Prunes. He also appears on the covers of the early EP Three, two of the band&apos;s first three albums (Boy and War), and Early Demos.</review>

+    <biography>U2 are an Irish rock band from Dublin. Formed in 1976, the group consists of Bono (vocals and rhythm guitar), the Edge (lead guitar, keyboards, and vocals), Adam Clayton (bass guitar), and Larry Mullen, Jr. (drums and percussion). U2&apos;s early sound was rooted in post-punk but eventually grew to incorporate influences from many genres of popular music. Throughout the group&apos;s musical pursuits, they have maintained a sound built on melodic instrumentals. Their lyrics, often embellished with spiritual imagery, focus on personal themes and sociopolitical concerns.&#x0A;The band formed at Mount Temple Comprehensive School in 1976 when the members were teenagers with limited musical proficiency. Within four years, they signed with Island Records and released their debut album Boy. By the mid-1980s, U2 had become a top international act. They were more successful as a touring act than they were at selling records until their 1987 album The Joshua Tree which, according to Rolling Stone, elevated the band&apos;s stature &quot;from heroes to superstars&quot;. Reacting to musical stagnation and criticism of their earnest image and musical direction in the late 1980s, U2 reinvented themselves with their 1991 album, Achtung Baby, and the accompanying Zoo TV Tour; they integrated dance, industrial, and alternative rock influences into their sound, and embraced a more ironic and self-deprecating image. They embraced similar experimentation for the remainder of the 1990s with varying levels of success. U2 regained critical and commercial favour in the 2000s with the records All That You Can&apos;t Leave Behind (2000) and How to Dismantle an Atomic Bomb (2004), which established a more conventional, mainstream sound for the group. Their U2 360° Tour of 2009–2011 is the highest-attended and highest-grossing concert tour in history.&#x0A;U2 have released 13 studio albums and are one of the world&apos;s best-selling music artists of all time, having sold more than 170 million records worldwide. They have won 22 Grammy Awards, more than any other band; and, in 2005, were inducted into the Rock and Roll Hall of Fame in their first year of eligibility. Rolling Stone ranked U2 at number 22 in its list of the &quot;100 Greatest Artists of All Time&quot;, and labelled them the &quot;Biggest Band in the World&quot;. Throughout their career, as a band and as individuals, they have campaigned for human rights and philanthropic causes, including Amnesty International, the ONE/DATA campaigns, Product Red, War Child and the Edge&apos;s Music Rising.</biography>
