Disclaimer: I purchased this for the microphones. It appears that there is a high failure rate with the Mics from SingStar bundles. I saw a review that indicated a player was using on his PS3. The Mics worked fine with the PS3, but the songs and disk didn't. I have a new slim PS3, older ones may be compatible but newer units definitely are not.
That said, we have had loads of fun with Sing Star.Get more detail about SingStar '90s.
