Jailbreak is out of question for you since the iOS version is 6.1.3 which is non jailbreakable and will probably stay that way. Hard luck on that front.
Let me warn you that this is a iOS device and do not treat it as an android else you will be very very disappointed and frustrated due to restrictions the device may pose in doing trival tasks.
Coming to copying songs, the only proper way of doing that is unfortunately itunes.Assuming you have songs on your PC/Laptop that you want to put in your iPod, i suggest you open iTunes and go to
File -> Add folder to library and add all the music folders together in one go to iTunes. In this way you can also manage your music through iTunes.
Now assuming you do not want all your music but only selective ones, i suggest you make a playlist so that you can sync that playlist with your device (rather than entire library). Add the albums and songs you want to this playlist, all from iTunes. You can right click an album or individual song to do so.
Remember that if your music folders already have the m3u playlists then those will be listed under iTunes, you can ignore those. Just concentrate on the playlist that YOU just created.
Now connect your iPod to your laptop with iTunes started. On top right you should see your touch listed, click that and you will be on main tab in iTunes "Summary" with a pic of the touch and some information like serial number, space etc.
Go to Music tab and check the box that says "Sync Music" and then select the radio button which says "Selected playlists, artists......."
And then from below select YOUR playlist and click SYNC (bottom of iTunes) and then you will start seeing that songs being copied to your iPod.
After sync is complete, click DONE on top right and check your MUSIC in iPod and see if all songs have come or not.
