Virtually all MP3+G™ songs worth having come from commercial karaoke CD+G discs. It is illegal for websites to give these files away. Any website that offered free downloads of these MP3+G™ songs would not be online for long. You can hit the back button on your browser and keep searching if you want but you will not find any websites giving away quality MP3+G files. Read on if you want the facts.
So where do people get free karaoke MP3+G™ files? Basically, one of three places.
File Sharing Channels
Definitely the most viable option, these channels are where virtually every karaoke song ever released can be found and downloaded. Most of these channels require that every member have a working file server and are actively sharing files.
The KaraokeInfo website sells a guide, with step by step instructions and required software, that makes downloading free MP3+G™ files easy. They teach you how to set up an IRC client (included) for file sharing and downloading. This can be a daunting task on your own, especially for someone who is not computer savvy. You're smart to be leery of this type of thing although people have commented to me that this is the real deal.
Torrent sites, and programs like LimeWire that access the Gnutella file sharing network, will often find those sharing karaoke files.They will even more often find computer viruses.
Some newsgroups, like alt.binaries.sounds.karaoke, have karaoke files posted by users for download. Requires a knowledge of newsgroups and binary downloads. Many ISPs no longer provide newsgroup access.
