That is one of my problems. Things like Thumbprint and Add Variety options are not there. I cannot see them. I tried in the iPad and iPhone apps and on my MacBook Pro via the website. The website states it is the new version and they haven't added the ability to create stations yet. I cannot find a link to the Classic website. Very frustrating! Their help is text only and they talked about the options you mentioned, but the options are not showing up anywhere. They really need to show some screen captures in the help. It all sounds easy to do, but not so much if those options are missing.

What I would love to create is a super station that was based on a few dozen performers and bands. All I can see is creating one based on a single performer/band or song or genre. That kind of station would be too limited for my tastes. I get bored with stations that only play a handful of performers and bands and just keep adding more songs from them rather than featuring songs from hundreds of performers and bands. I guess my old school idea of a radio station must be way different from what Pandora calls a radio station. Amazon was just a bad in that regard. I really don't like hearing the same performer every 5th or 6th song.
