How to sync music to my iphone without erasing everything?

On my computer I wiped the whole computer then I installed iTunes again but I get all my music for free from other sites so when I try and sync it won't work I've done the manually move that says erase and I've done the sync music it says the same and this is the original computer it's been on so how do I sync new music to my iphone without removing everything?

Use winamp instead of itunes.i'm not 100% sure if you can use it with the iphone but I use it to sync to my ipod. You just select the music you want, right click and then send it to whichever device you want without having to erase any music that's already on there.
