Should I keep doing future updates to my ipod touch?

Dear Apple Support,

I've always been skeptic about this random ipod touch software updates. I don't even have count of how many times I have actually uodated my ipod. My point is that I updated my ipod today, January 19, 2012, and for the second time it erased all my apps and music.While doing the update it said all my music, pictures, apps, etc was being backup but it didn't. Where I stand right now I think it is really unfair that apple is providing updates that are causing for us to loose rather than to gain. I know this message won't make a difference because I won't get back all my 3000 songs. Apple may be a really presticious brand to own but not as efficient as I thought it would be.

Sincerely,

Stephanie Prado
