I personally loved This Is the One. I definitely sensed the quirkiness of it the first time I listened to it but I didn't feel like it was out of place. It felt like she was definitely being herself (yes, even with On and On). It felt like it was an album she had fun making and was able to let loose while doing so, which is why the album is a bit odd (for Hikki's case at least) as a result.
@zahara: Mosh pit? At a Hikki concert? I guess New Yorkers will be New Yorkers... I'm glad you enjoyed it.
