Replying to ITunes !

i need a bit of help.

Finally its time to get an ipod, so its time to ditch good old windows media player and get all my music into itunes.

When i click import.. i have SO many songs to import, but it wont let me highlight more then one.. is there someway to get past this? Like.. it will take a month to import every track one by one.. im sure its something simple and i feel like a noob, but an answer to this would be appreciated.

thanks guys
