British pop star Lily Allen has endured "exhausting" and "frustrating" battles with her record label over her music comeback.

The Smile singer recently hit headlines when she agreed with a fan who called her latest singles "docile pop rubbish" and she blamed bosses at her record company for failing to promote her more dynamic work.

Allen has now opened up about the troubles she has had with label executives, claiming she was left furious by some of their decisions.

Speaking during a panel discussion at the Vogue Festival in London on Sunday (30Mar14), Allen explained, "I experience it (the idea of playing it safe) at the moment re-entering the music industry. What you have heard on the radio station so far, the contribution of my album is very much the more beige, saccharine elements to what I have made.

"The reason for that is because the people in control of the radio stations, the people that are in control of the record companies, are too scared to put themselves on the line in case someone gets offended.

"If I said to my record company I really want to go with this song, they would say 'Sure, here is £5 for the video'."

Allen goes on to reveal she often fights with her bosses in a bid to take her career in the direction she wants.

She adds, "I am part of a machine. I do not necessarily make the decisions I would make for myself as an artist. I am owned by a multinational corporation. No one makes me do anything because I can put my foot down but it gets f**king exhausting having to argue with people all the time. You just pick your battles."
