If you believe everything you read, the sound at the Spice Girls' recent comeback shows has been zig-ah-zig-awful.
Some fans who attended the opening night in Dublin complained about muffled vocals and being unable to hear the band speaking between songs.
Mel B acknowledged the issues in an Instagram video, saying she hoped "the vocals and the sound will be much, much better" for the second show in Cardiff.
Spoiler alert: They weren't. But by the third date in Manchester, reporters said the sound was "crystal clear".
But it's not just the Spice Girls who have suffered from sound issues this week.
The Strokes were beset by problems when they played their first UK show in four years at the All Points East festival in London on Saturday, with one fan comparing the gig to "underwater karaoke".
The audience was filmed chanting "turn it up" during their set, while another festival-goer complained: "If you want to replicate the experience of going to @allpointseastuk put your laptop volume on 50% and stand two rooms away".
Over the last few years, outdoor shows by Eminem, The Killers, Blur and Paul Simon have all been criticised for low volume and poor audibility.
