ive got itunes but its just a bit of a pain in the arse if you ask me. its to hard to find a song and sometimes when searching for them you get matchs that are no where near. WMP is s much better IMO!
I use windows media player. iTunes is ok when you only have 1000 songs or less, but after you get about 8,000 it gets extremely laggy and takes up a lot of resources. Windows Media Player works great for me.
iTunes, doesn't freeze like wmp, easy to use, can stream music around the house, works with my ipod, it has the music store, and I just generally like it
