It really gets to me when people berate my music tastes. I like a mix of things, but not much that's popular (Justin Bieber, One Direction, will.i.am and Little Mix can all shove it). It's up to me what I listen to, but I'm used to people not knowing/liking the same bands I do. I think if they want to listen to 'J-Biebz' then they can, but I'm going to enjoy The Tease, Oasis, James Vincent McMorrow, The Smiths, The Bee Gees, Newton Faulkner, Lupine Bell, Alice in Chinatown, Dido, Washington, The Travelling Band and Ben Folds.
Having said all that, I actually quite like Ed Sheeran and Florence + The Machine at the moment...
...and Mumford and Sons. And The Vaccines.
