I added all these songs into my new computer using my ipod. But when I took the ipod out, none of the songs work. They all have an exclamation point next to them. I know this means that there is no actual music file in my itunes folder. I tried to add them again, but had no success. I don't have my ipod anymore, and I don't like all of those songs taking up space. Is there any way I can just delete the songs with the exclamation point next to them from my library and keep the rest of my music? Thanks.
