RTFM
You need to put the Fuze original firmware USB mode to MSC, then just copy whatever you want over.
The other crap that is on there was already there, just hidden from you by the Sansa firmware. If the names of your songs annoy you, then rename them. Nothing to do with us.
The other alternative is to use the database. Again, see the manual.
Oh, and I'm very sorry but we are not willing to violate copyright and distribute other people's software without permission just to make it marginally easier for you.
P.S. If you tried to write in proper sentences it would be much easier to understand you and you might get more help.
