How to re sync music to my iPhone 5?

How do you re sync music back into your iPod, I recently rebooted my computer along with all my old songs. Now I can't download anymore new songs.

You can use iphone/ipod/computer transfer software to copy Apps, Contacts, Songs, Videos, Photos, Playlist, Games, etc between iphone 5, ipod and computer. Here's the one I used to use http://www.001-software.com/itransfer/index.html

hope this helps.
