I use Limewire too. I open all of my songs with Winamp (you could use any mp3 player) and then I burn them onto a rewritable CD (CD-RW), then I import the songs to iTunes. Not only are the songs in iTunes, but I also have iTunes set to import songs at 128 kbps. That's CD quality, anything more just wastes space on your hard drive. Then I put them on my iPod. If you used a rewritable CD, you can just erase it when you are done. It can be a pain to do this, but a lot of songs on Limewire are more than 128 kbps
