On certain (edited) songs they still sometimes leave like the CK sound on the end and you can easily tell what they say I wanted to know if there is a program out that I can get that I can completly cut out those last letters heh. IS there one?

hew SUPA...check ur pm inbox thingo....

Cool Edit, Wavelab, and SoundForge are all decent programs for audio editing.

It is difficult, however, to completely bleep out words without effecting the music part of things. Unless you can get the original a capella (vocals) and instrumental tracks (like on a 12").
I wouldn't worry about a left over syllable on an edit. As long as the majority of the word is gone, you should be fine. I.E., if it's played on the radio, it's ok.
This is where music services come in handy.
