Oh! Thanks for the clarification, @jbosek!
In your original post you mentioned "I stream through my TV and I can't figure out how to add new artist?" - I've moved your thread to our Desktop App to help keep things tidy.
Adding variety on web or through the desktop app is super easy. Here are some steps:
To add variety from a computer, click on the name of the station you'd like to edit. If the station is not available from your Now Playing page, click on the My Collection button first, sort your collection by Stations, and then select the name of the station you'd like to edit. From there you can Add Variety to your station by scrolling down to the Station Created From section. Then choose + Add Variety. Please note: You won't be able to Add Variety to your Thumbprint Radio, or to genre stations curated by Pandora. Next, either enter the name of another song or artist, or roll your cursor over a suggested artist. Whichever you choose, hover your mouse over your selection and click on the "+" sign that appears to add that seed to your station.
