splitting music files-what program do i need?

[STPHNSN23]

i've been getting some music off of mIRC, but the files are big. they are the whole albums in one file. i need to break them up into tracks so i can burn them onto a cd and jam in the car. what program should i use to split them. the problem i am finding is that most of the files are .rar or .tar format and most of the programs will only split .mp3 or other more widely used formats. thanks
