Deauthorising doesn't do anything to the song files on your computer, it simply means that the will not play (if they are DRM protected) until you reauthorise the computer. However you should be aware that all your purchases should be backed up regardless so that you can restore them if you have any problems. Remember that the policy on iTunes music purchases is that you only get to download them once so if you haven't already done so, take this opportunity to back them up:
How to back up your media in iTunes
Back up your iTunes library by copying to an external hard drive

That's incorrect in the context. The Deauthorize All function doesn't change anything on the computers, including the local copy of the authorization record.

my brother had itunes on his computer but it crashed. so if i deauthorize all, then if i authorize a computer, ill still have all of my songs?

You need to have copies of the songs to be able to use them. If you don't, you need to download them again. Click here and ask for a free redownload if needed.

+So if i dont have any traces of them on my computer then I won't be able to have all my songs when i authorize a cmputer?+
No. The music files have to be on a computer to play them, just like any photo files would have to be on the computer to display them.



+how do i ask for a free re download.the link just took me to a main page+
You read the page closely and click on the correct area that links you to the request form.
