Transfer iTunes play count data from old laptop to new Macbook Pro

I have just purchased a macbook pro. Previously I had a Dell laptop running Windows 7. I had stored all my music on an external harddrive, I have successfully transferred my music to my new iTunes library. However, all the songs have no plays, is there any way I can transfer this data to my new macbook?

I also need to transfer iPad 4, iPod Classic and iPhone backups to the mac.

Any help is greatly appreciated.

Thanks
