Miley Cyrus was on The View recently where she stated that after her next album comes out, that will be the last thing she does musically for a while.
"I have a record coming out in June and that's going to be the last thing I do in music for a while. I just want to do films 'cause I like being someone else. My music is kind of like my diary. I'll always do that... I just feel like the music industry isn't as positive as I'd like it to be."
Personally I think this is a good decision. While Miley is probably a better singer than actress, she has already recorded a ton of songs. I think people might get burned out on her music if she does too much too soon.
