Mixing filler music between singers?

[ursongs]

After 3 years using hoster, then finding another software to make show better, coming back ....(compu host has glitches during music, and timing of music and words highlighting is not good.) need to find a better way to fade filler music like compu host. Hoster plays karaoke better and tools better. Does anyone know how to fade music instead of wam bam after dead air space. (with Hoster) Have to get creative announcing between songs now.
