Hassidic pop

Some guy posted a comment on my blog alerting me to this ultra-orthodox Jewish music site (in Hebrew). There's some interesting stuff on it, including this  youtube video by Lipa for a song called 'Diet'. What's interesting is that it's a light-hearted song (in Yiddish) about (presumably) food with a similarly light-hearted video. I'd always thought that one of the things that defined the ultra-orthodox community was it's shunning of more trivial musical themes  - apparently that's not the case.
