Please don't bother with posting if you have no idea what you're talking about.
CUERVO,
iTunes and iPod are fully capable of handling MP3's. In fact, it is the only format I use. How exactly are you trying to import the MP3 you downloaded? Are you getting an error message or is the MP3 showing up in your library as gray? Have you tried simply clicking on the file and dragging it and dropping it into your iTunes library?
Also, keep in mind that when you add files to your playlist, you don't use the Import feature. You are actually supposed to go to File > Add File to Library. If this isn't what you are doing, give it a try.
Do either of my suggestions work?
