While driving I ask Siri the name of a song playing on the radio, how do I retrieve the answer?

[iMore Question]

Siri answers the question but I have to wait until later to read it, how do I retrieve the answser later

Go to the iTunes app on your phone. Then click the 3 list bars in the upper right. Then click the Siri tab to see all the recent "What song is this" results.
