Hey Mike,
Are you setting the songs with WaterMarks every 15 seconds on purpose?
Are you turning the Musix down 100% during the watermark audio on purpose?

We'd like to enjoy and feel the entire impact of your songs so I hope you don't mind...Just a suggestion...
Move your watermarks to every 30 or 60 seconds.

Reset the WaterMark volume balances; Set the Song Volume at 60% or 70%. This way the song doesn't STOP when the watermark appears.
Right now you have the song reducing 100% when the WaterMark arrives...this blacks out the song altogether. Personally, it's breaking the grove of your music and making the storyline harder to follow. It's all about GROVE and WORDS right?

As always, It is your prerogative, however, I think you can protect your Musix and give the listener a pleasant experience at the same time. You can have both worlds if you just adjust the balances a little.

You can adjust your watermarks where you upload your Musix in the first place.
NEW...You can now create a "custom watermark" using your own voice and your own message!

Just a suggestion.
