How to erase music from itouch?

ITOUCH PROBLEMS- HELP!?

• I turn on my itouch first generation with 2.0 software, and click music icon and it says "no music,download from itunes" and it says the same when i click on videos icon but "no videos".This is weird becasue a few days a go i had tons of musci and three videos. I plug it into my computer and my ipod shows up on itunes and it has under it, music, videos, tv shows, 90's music, etc. and all of the stuff that was on my ipod is there, like it was when it was on my ipod and computer . None of it is in my library becasue i get music from someone else. I tried backing up and nothing changes. Sync says tht it will erase my whole ipod musci and put whats on my library to my ipod,no library though. What do i do? If i restore will my music still be there, all my apps be there? HELP! ----So its not on my ipod or itunes when my ipod is not connectes. I plug it in and under devices category music its all there,,,i backup and still not on ipod!!!
