technology is great!!

NOT!! its really getting on my nerves that I had to buy a new computer, have to put all my music back into a new itunes (6000+ songs) and now its not reading the artists and song names so I have to put them in manually, that is way too time consuming!! why cant they just make things easy on me!! I am getting tired of this already, and have only done like 70 songs!! I bought an apple so that it was all the same. I have a apple computer, ipod and phone, why cant they all just work together!!
