Microsoft Zune, I can put regular MP3 files, or do I have to go ZunePass?

I have looked through many Zune FAQ and I have yet this simple question to be answered before considering buying a Zune HD. I have heard much about this thing ZunePass as iTunes, and that's a good thing to have, and probably will use from time to time .. But what I want to know is – all mp3 that you download and listen regularly Limewire on my Windows Media Player – I will be able to put on my Zune? I heard a rumor that the type of Zune "opposes" any mp3. files that have not been legally acquired or specifically Microsoft.com. I have hundreds of songs in my Windows Media Player, technically, was pirated. I have no desire to go and pay a dollar for every one of them to put them on a portable mp3 player. Has anyone experienced this or heard anything about it? No one bought a Zune and Limewire loaded successfully acquired the files in it? Thank you.

Yes you can do that, no limits
