yeah, i have heard of all the other gimmick cds

problem with these things is they sometimes don't work in all
players depending on the  disc width and other things (ie, older cd 
players, multi-disc
carousels)... the shape cds are especially bad....


  i am assuming the vinyl side can only hold 3-5 mins at 45rpm
and maybe 10-15 mins at 33.3
