yeah I prefer grooveshark as well..
now one of you show me how to embed grooveshark playlists
as far as vimeo goes, most vimeo won't embed because if the user has a + account, it's non embeddable unless the user specifies where.. if it's not a plus+ account, then often times everything is just disabled as a default. Been working on this forever..haven't found a way around it yet.. so the links will just have to work.
