Hudson has revealed details for its upcoming WiiWare title currently known as Karaoke Joysound. Hudson hope to have 20,000 songs available at the start of service for the karaoke title and will add 1,000 every month. Hudson has plans for a subscription service rather than you having to pay per song and it is assumed this will let you download as much as you like over a set time. The title is expected to be released in Japan this Summer.
