The impact of music on a film’s quality can be significant; a strong soundtrack can really elevate things. It establishes the mood, dictates the feeling, and often serves as the emotional core. Guardians of the Galaxy 2 isn't exactly a masterpiece, but the music pulled it back from being truly awful. Conversely, Ibiza suffered greatly because of its soundtrack. When I say it was bad, I mean it was so unpleasant that I had to leave the room my girlfriend was in just to get away from it. The primary issue was the audio; the music was excessively loud, inescapable, and if you lowered the volume, the dialogue became nearly unintelligible—which wasn't a significant loss, frankly. What unfolds on screen is interspersed with scantily clad performers, then relentless house music, the kind of repetitive three-beat rhythm from a drum machine played at an ear-splitting level that prevents any coherent thought...followed by snippets of dialogue, and then more of that same house music. Occasionally there are actual songs—also featuring drum machines and auto-tune, rendering them indistinguishable from what’s already on the radio—and these are blasted at a volume far exceeding everything else in the film. What's the plot? It doesn't matter. The brief moments of quiet between the awful music offered only temporary relief before another wave of intensely irritating sounds arrived. I’ve endured many terrible movies, but I’ve never been as bothered by a single film as I was by this disaster. If you enjoy listening to distorted recordings played at deafening volumes, then this movie is perfectly suited for your tastes.
