ahaha i found ma self in that same situation, also wen i burned the cd's into data disc format yh u can get loads of tunes on it but im seeing a few problems with filling the cd right up over 3/4 with tunez.
i put in less the 2nd time and had no problems . they were mid range cd-r's but not really anything to be complaining about lol.
i like how the decks can take data discs, sum ma mates sayin citroniks isnt tthe best make , and i can tell they far from pioneers but i think they pretty good for the price and for the mp3 compatability also the data discs u can use on them as well. and the samplers a good touch, i wud probably rate them 4/5
