What's that song?

A description of how technology, data access and my behavior have changed over time.  How I discover the name of a song when I hear it on the radio:

• Stage 1 (decades ago) - Contact the radio station
• Stage 2 (years ago) - Check the playlist on the station's website
• Stage 3 (months ago) - Google unique lyrics
• Stage 4 (now) - Use Shazam

I wonder what the next stage will be.
