Adding silence between playlist tracks

[FGD135]

Hi

I would like to know if there is any way to add 4-5 seconds of silence between playlist tracks.

I could open each (of hundreds) track in Audacity, add the silence at the beginning of each track, then re-save as MP3, but 1) take way too much time, and 2) don't want to risk quality decline due to re-compression.

Can anybody help me out here? Should I add this as a wishlist item?

Thanks.
