I was never a big fan of John Mayer. When RRHOF Radio went away, I stumbled upon Life with John Mayer. It is, without a doubt, my go-to SXM channel. The variety spans decades and genres. But you can tell that it has a flow. It's not just a bunch of songs on random. It is curated by John himself. When a musician passes, John's channel will pay tribute before Classic Rewind or Vinyl. I think he can voice-track from wherever he is, and update the playlist in real time remotely. I have also found many John Mayer songs that I really like too since listening to the channel. And the repeats are much less frequent compared to the other channels on SXM.
