On the local radio station here in the Czech they announced simple
If listeners will hear Elton John's Sacrifice followed immediately by
Madonna's Frozen they have to call to the broadcasting. First caller
will get some price.

I am just thinking about the concept how to analyse music stream form
the PC radio card to get the signal: "first tones of Frozen were
played after Sacrifice, call to the studio" :-)

Of course, the calling can be made by PC as well, but this is the
easiest part of the task :)

Thanks for your tips and comments
