yea i found this one program that really easy to use to add effects and whatnot to your songs, its free too!!

greatest s**t ever!!!!

its called Wavepad, look it up on google.
just thought id put it out there.
be carefull where you download it from. i downloaded it from ares once and it dumped so much extra crap on my computer it was rediculouse. but if you just do it at like download dot com or something your probobaly good.
