If you buy songs legally from the LimeWire store then it will cost money. If you are caught downloading songs illegally without paying for them then it could cost you a lot of money. To quote LimeWire: What Happens If I Commit Copyright Infringement? Your activities on peer-to-peer networks such as LimeWire may be monitored by copyright owners. Violation of copyright laws may subject one to substantial money damages. Copyright owners have sued thousands of people for infringement of copyright over peer-to-peer networks. (See links below)
