An audio system malfunction at a school in Javalí Viejo, Spain, caused "Happy Birthday" to play for five consecutive hours during the night. Firefighters intervened at 4:30 am to shut down the music and end the residents' sonic nightmare.

A nightmare evening for residents of Javalí Viejo, a small town near Murcia, Spain. A malfunction in a local school’s audio system turned what should have been a peaceful night’s rest into a surreal forced concert: the song “Happy Birthday” blared continuously from loudspeakers for five consecutive hours.
The festive tune began broadcasting in the middle of the night, gradually waking up all residents in the area. Unable to fall back asleep and with no way to stop the music, the exasperated inhabitants had to wait for authorities to arrive.
Firefighters intervene at 4:30 am
Finally, around 4:30 in the morning, firefighters had to intervene to end the sonic torment. The fire crew reached the school and managed to shut down the malfunctioning audio system, finally restoring silence to the neighborhood.
The incident, while annoying for those who experienced it, sparked hilarity on Spanish social media, where many joked about the peculiar nocturnal “serenade.” It’s still unclear what caused the technical glitch that sent the famous birthday melody into an endless loop.
@greenme_it A Javalí Viejo, frazione di Murcia in Spagna, i residenti hanno vissuto una notte da incubo: un malfunzionamento dell’impianto audio di una scuola locale ha fatto risuonare in loop la canzone “Tanti Auguri” per ben cinque ore consecutive. Il brano festivo, partito in piena notte, ha costretto gli abitanti a rimanere svegli fino alle 4:30 del mattino, quando finalmente i vigili del fuoco sono riusciti a intervenire e a porre fine al concerto forzato. . . . #greenme #greenmeitalia #BuonCompleanno #pompieri
