best audio burning software

i used CDburner XP for a long time for just data cds and it worked great but for audio cd it really SUCKS. for some reason, every time i try to make an audio cd (not mp3 btw, just a normal audio cd) it adds about anywhere between 5-20 minutes of silence to end of every track. i mean audio cds are only suppose to hold 80 minutes and with 10-30 minute songs for 10+ tracks is just to much so it shouldnt even work. but anywhoo what would be better to go with, for free anyways. i dont really wanna buy 1
