For most bands, there will always be that one specific song that's synonymous with their legacy. For Oasis, it goes without question that it's "Wonderwall." It is undoubtedly the biggest song the English rock band has ever produced and one of the most iconic tracks in the history of alternative rock. However, despite the immense success the track achieved, it has also become a target for criticism, largely due to its overexposure in the years since its release. But it's not just listeners who have mixed feelings about the song; even the Gallagher brothers (Liam and Noel Gallagher) themselves aren't entirely fond of it. To say it's their least favorite would be to take it lightly. Liam has even gone as far as to say the song makes him want to “gag.”
