Bob,
Your question was about CD+G.
A CDG song take about the same hard drive space as WAV file. That’s 10.6MB per minute. For a 3:30 minute song, that’s is 37.1MB.
True, you can compress songs but they will no longer be playable on a regular Karaoke machine.
To give you a compression example, MTU has a program called "Hoster" that's designed to run a complete Karaoke show right off your hard drive.
Using a 96KB WMA compression, you can have over 8,500 songs on a 40GB hard drive.
Here is a link if you want to read more about Hoster:

P.S. 30,000 CDG's? You are talking more than 300,000 songs! I didn't know there were that many out there. That's enough songs to sing around the clock for more than 600 days.
