There's no page here for downloading music...this is a help forum only. Do you have LW installed? If not, download Java first from this link: Java SE Downloads
Use the JRE offline installer & remove any other Java versions installed (via add/remove programs) before you install this one.

Next, use this link to download LW: http://www9.limewire.com/download/LimeWireWin-full.exe

Once you've installed LW, read through the User Guide - LimeWire and Frequently Asked Questions - LimeWire

And if you already have LW installed, check out this thread for info about adding files to iTunes & iPod: How to transfer music to my iPod (& iTunes)

Please let us know which OS you're using, so we can move your post to a better place
