hey- i'm using a mac and i can't get anything to play even when i open iTunes. I have songs in the library but it won't let me drag them into iTunes. Can anyone help me?? Thanks...

You can't take them from the LimeWire Library to a player. You have to take them from your Shared Folder (found by default in your Preferences Folder) You can move it by going (in LimeWire) to: Tools > Options > Shared and add a folder of your choice to download files to and use them for sharing/playing.

make itunes your default player. then just click on what you have downloaded and it should play automatically. Tip: if you have to keep going through the menu's to get to your shared folder assign a function key to the shared folder then ther will be no more searching for your files.

How do you set a default player?

To set itunes as your default player.
open itunes
edit
preferences
in the general tab there should be a button called "set itunes for internet playback"
click this and you are all set.
