You can use these to practice/learn any instrument or vocal by muting that track.
Here are some free multitracks with video lyrics to test:

there is a link for the video
Karaoke Video with Lyrics mp4
You can set Biab to a BLANK style and set the tempo then drag import each track.
If you want a 2 bar count-in set it to import 2 bar offset when drag import.
You need to right click track > Track Settings > Set Base Tempo to the tempo of the tracks.
To get the video lyrics rename the .mp4 the same name as the SGU and it should load in and play with the song, I don't know if there is an offset to start the video 2 bars later if you added a 2 bar count-in when import tracks ? If it loads the video to the Audio track just mute it.
PG needs to get the play direct working so it don't convert each compressed file to a 32bit wav file so it goes from a few meg to a 90meg wav file !
If you have the CDG lyric file it won't show unless you open it separately, if there is a CDG file the same name as the SGU Biab should use it but it don't.
