Is there anyway i can update my jailbroken iPhone 5 to ios 7.1 without losing any of my music?

All my music is from mewseek and other cydia apps and i want to update my iphone but i don't want to lose my music.

When you jailbreak your phone, you void the warranty and if you then update it to the current OS, it WILL wipe out what you have on your phone because none of it came through Apple or Apple-authorized apps.
