What I have heard is that these sites offer WMV format and not MP3+G because their license is only valid for personal use on a home system. The theory is that it is more difficult to take WMV to a bar than downloaded MP3+G. A couple of sites I saw that offered both WMV and MP3+G discontinued the MP3+G. That said I have been reading their vague licensing statements (if they have any) and found none that state "for home use only", which tell me they are trying to sell to as broad a market as possible and let the buying worry about legal use. SO I suspect the licensing organizations got on their case about offer MP3+G formats.
I have tried to get clarification from download sites as to what their license covers, but any answers I got (and not all answered) were equally vague. As a result I have yet to purchase any download karaoke.
