With the Title page enabled, music starts 15sec in.

[Roy Dennis]

In the instructions it states:
(If clicked checkbox Enable this page is checked, the Title Page that you define appears before the song lyrics start. It adds silence for 10 seconds plus the Hold: time to delay the music and lyrics so the page can be viewed. It may overlap the starting music if the lyrics start after the musical introduction.)

My own testing on a song I tried I reduced the Hold Time to Zero
And the music started within a second of starting the song.
I did not use a graphic on the start screen just text.
The music is full vocal I did not reduce vocals on this sample.
What version are you using?

The other point is when playing in Hoster you can set to remove silence on all songs that have been imported into the database.
