i have this file

and it's a concert

but there's gaps of silence in between

and i wanted to fix it so i could like "cut" it into songs

is that possible?

do i need a program or something

You should be able to use any digital audio software for that. Pro Tools, Cool Edit, Cakewalk, etc., would all work fine. There's a free version of Pro Tools available on their website that would work fine for that, but I think it only works on Macs or computers what use Windows 98. Otherwise, get on Kazaa or whatever you use and search for something. Most of them are pretty easy to learn how to use.

Cool Edit is good.

pretty much any standard wave editor will do fine for a job like that.

anything that's free mind you...

everything can be free ;)
