Short pauses between Songs in Playlist

Hi folks.

Another question about the same subject:

Is there a loading time between 2 songs (multi tracks) played from a playlist, or the time between two songs is just the time for my finger to go from the instrument to the LP16’s “play button” ?

Another question:
How many songs (still multi tracks) can I have on my HD being played from the same playlist?

Thanks for your answers.
