'Listening to music' is not added to multiple-tasks

I play a vanilla game on PC and couldn't get the knit while listening to music for the Lady of the Knits aspiration to complete.  I tried different radios and then selecting listen to music first, when the sim didn't automatically turn on a stereo like sims usually do.   After trying for two real life weeks, I gave up last night and used the aspiration cheat to complete the milestone.
