Can viruses infect your music and other files?

I got a virus (somewhat nasty one - RootKit.0Access.h) and I am going to clean install my computer. However, there are some files (mainly music) that I never backed up before getting infected. Am I safe to just back these up now and transfer them?

I'm just not 100% familiar with how/where the virus might spread and if your personal files can carry the infection to the newly installed system.

Help appreciated. Thanks!
