It doesn't matter what MP3 player you have. You cannot get good free music legally. Some play different things. Like,
Walmart doesn't work on iPods, and iTunes doesn't work on all players, cause they are different types of files. But, anyway, free music is illegal, and so many viruses get transferred from Limewire. I would not use Limewire, cause who knows what else you're getting with the song. I would just use iTunes, or Walmart or something. It's 99 cents. Walmart 88. So, yeah.
ETA- I completly agree with Sparx. I have very strong feeling againt Limewire, also. I just use iTunes.
