Lips original disc reset to 0 songs...??????

[DUBBLEUP]

My first lips game was party classics, then I moved onto Number One hits. I recently purchased the original lips disc, however when I click on sing the 120 song total depletes to zero and then displays a message "Cant enter this menu because your music collection is empty. Make sure that you are singed into a gamer profile and go to Get Music and add songs"
Whats this all about?
I'm obviously logged into my account and ever other lips disc works perfectly. I even have a few songs downloaded onto my harddrive, but yet my music collection is empty? Is there someway around this?

Not sure if this is the problem but try going into GET MUSIC and hitting the BACK button on your controller. Make sure all the icons are highlighted and not greyed out. Hit the A button on the icons to light em up. Now try going back to SING and see if they show up.
