I totally agree. She has changed. Also when she first debuted her and her piano or keyboard were always together in videos and performances but with the last couple of singles she's not seen on the piano. Even though the piano is still used in the song, she's not seen playing it anymore. I wonder if she's trying to separate her image from the piano. Like Angela Aki's and Alicia Keys' images are connected to their piano.
@rookies A podcast is usually a video or audio file. People usually record themselves having a discussion about some issue or current news. Then people download it and listen to it on their iPod or other mp3 player.
There are different types of different subject types. Like you can get one where the discussion centers on politics or music issues. Or the one sora and emiko are talking about is here
