Karoake tunes are remakes of just the instrumental tracks by other artists in most cases. If it sounds like the original music then it's either a really well done reproduction, or they went back to the masters and dropped out the vocal tracks.

For drums, about the only way to properly duplicate a song is to do it manually and spend time at it.
Find samples that sound close to the original and put a 'kit' together. Then either build up your own midi track or find one on the net done by a pro.

It takes forever to do it on your own unless you've ton a ton of them and have some experience at it. Besides finding similar samples, you also have to pan them correctly, use the right reverb and room sounds and then subtely put timing errors into the tracks to make it sound like it isn't a machine playing.
