I have an ipod shuffle and it says its synced to a different itunes want to add more songs

SO I have an ipod shuffle that I use for working out and when I connect it to my computer it says its synced to a different itunes and I do not want to erase it all but would like to add more songs how can I do so?

I thought I read somewhere that it is possible to change it so taht it works like a hardrive but not sure but I would like to add more songs if someone could help me out that would be great!

Thanks

 

anyone please help?

 

it has to be synced with only one iPod, so you should probably re-sync the shuffle with all the songs with one library again.

 

isnt there a way to make it into a hardrive so you can add and delete songs instead of going through I tunes?

 

no, the shuffle can't be made into an hard drive
