>But if there are the same albums on both machines wont it over right them
Yes...it will on the first restore that you do (though you can tell MSB not to). You'll have to decide which machine's directory is the master...and which is the slave. All changes to files in the master will be reflected on your slave. But that should be OK because you wanted total sychronization between the two.
For simplicities sake...
If you know your master contains everything you want for both machines, then I would delete all the files out of your music directory on the slave and restore the first Normal backup set. This sets them both to the same baseline. Any changes made to the master will be reflected on the slave...but of course, the reverse is not true.

PS: I assume your running the same OS on both machines? (or at least from the same family...such as NT/W2k/XP OR W9x/ME)
