You can easily get the platinum record for the song ''It's the End of the World as We Know It'' by singing the note for the phrase ''Eye of a hurricane....'' and just holding it out for the entire verse (don't worry about lyrics)

After loading a song, eject the disk and the music will stop playing, but the words will continue to scroll. Sing. Eventually, re-insert the disk and the music will load, but in the same place it left off. Press pause and un-pause and the music and lyrics will be in sync. Repeat if wanted. Now you can get a higher score on harder levels.
