iTunes is definitely not one of my favorite music players, and thanks to Keshav who showed me how to use a barebones player and convert Foobar2000 into a super music player, I have been using it more and more.
Of course if you have a iPod or iPhone you do require iTunes to transfer and manage music. But there are iTunes alternatives like Floola and iPhone PC Suite.
If you do not want to use a alternative but just want to export MP3 songs and albums for iTunes, iHandler a Adobe Air based application can definitely come in handy.
The software will basically allow you to load a iTunes Library and export the songs and albums and allow you to store it in another folder so that you can use it with other music players.
iHandler is based on Adobe Air so it can run on both Windows and Mac.
