How to import all of my music from my iPod to iTunes?

Four days ago, I got a new Lenovo laptop for my birthday. There was, however, one substantial problem: my new laptop does not have a disc drive. So, because of that, I can't insert my CDs to create my music library.

Is there a much simpler (and cheaper) way which I can import all my music?

If you still have your old computer you can share your Itunes library and export it via a network or flash drive
Go to iTunes help and search for "transferring iTunes library to a new computer"
If you no longer have your old PC/laptop you can transfer your songs from your iPod to your new laptop, however you will have to buy the software
Just google ipod to Itunes transfer
