Propeller Arena soundtrack in Virtua Tennis 3 demo?

I found out about that right after starting playing the PS3 Virtua Tennis 3's demo. I played PA to death and it was really easy to remember the tracks (very nice songs btw).

Found a video about it:

Someone else noted it?

 

I have played both games but I never noticed this. Someone at Sumo Digital
should know

 

Sega got its music from two places when it decided on the soundtrack for Propeller Arena: Fat Wreck Chords and their own in-house studio. I believe those tracks are from the latter. A shame that since they wanted to use them so badly, they didn't just go ahead and release Propeller Arena.

 

The full version also has the PA songs, altough more mixed.

 

Yeah, I wonder how often this happens with unreleased games.
