She says that the mainstream media are irrelevant, and then says she has interviews in an hour with BBC Radio 1 and Capital FM! These two radio stations are the very definition of mainstream UK radio
OK, Halsey. Try and be a bit consistent. You cannot say mainstream media are irrelevant and then talk about how MTV are helping promote you in the same interview. Then again she does acknowledge she is still trying to work out what her goals are with her music career, in terms of what she would regard as indicators of success.
She also sounds a bit ungrateful to Imagine Dragons. They were giving her an opportunity to grow her fanbase by opening on their tour, and she basically insults their fans. The onus was on her to win them over and impress them with her songs/performance. If she failed to do that to a significant degree then the fault is with her and not the fans.
I know that she is still very new to the music industry but she will have to learn quickly that things she say will now be reported, analysed, dissected and misinterpreted. Lorde intially went from someone who no-one cared about what she said, to the media jumping all over it. She then realised that she needed to be more circumspect about her public opinions. Halsey will have to get there too.
