I would agree with Lisa that 'profound meaning' does not have to be given to every (or any) magical effect. However, I do believe that an effect has to have context. To do the 'Color Changing Records' now would be to use dated material unless (context now) the magician is performing his magic in the character of, for example, a DJ or a character from the 70s or '80s. Another 'context' situation could be that the entire (or majority) of the act is all color changes of different items.
Since my original set was actual records, I started the routine by removing the playing record from the turntable and going into the routine. I felt this was a much more natural introduction of the prop then simply pulling it from my case. Something as simple as this can help to lend context.
A magician can aimlessly jump from trick to trick in a 'mall situation' where s/he is interrupting the shopping experience of passersby who want to stop and watch the act (and leave once they've had enough), but a paying audience is going to expect a bit more from the performance. Who do we remember more: Madonna or Tiffany?
