stay on limewire, go to Windows Media Player and click Sync.It should say something in the corner like,'drag items here'.then go back to limewire,click and hold onto the songs u want on ur Mp3 and drag them to the 'drag items here' spot. when ur done getting all the songs u want,click 'Start Sync' and ur songs will be transfered to ur Mp3!

for some reason,my ilo wont let songs onto it
