"The problem with karaoke video games is you're limited to a selection of songs on a disc. Joysound Wii tackles this issue by offering users all you can sing tickets. Pay 300 Wii Points and you get access to a library of 30,000 karaoke songs for 24 hours. That's not a bad price for an impulse purchase.
Hudson also has long term payment plans like 72 hours for 500 Wii Points, 30 days for 1,000 Wii Points, and 90 days for 2,000 Wii Points. For less than the cost of going to a karaoke bar on a weekend you can get one month of Joysound."
