That is an intentional effect, where the first 4 bars are intended to sound like an old AM Radio, and then it kicks in with the proper-sounding style at bar 5. That particular demo is one of the "Songs With Vocals" demos. For styles that have a "Songs with Vocals" option, the program automatically switches to the online version so that these demos will play rather than the original demos.

That being said, it would be great if the user could actually decide whether they want the original demo or the "song with vocals" demo. I will make a suggestion that that feature be added for future versions.
