Welcome to the zaz's music selections on Pandora. I am a long time Pandora user, and have created many stations. My current selection is a total redesign taking a focus on a single artists for each station. Many old stations were deleted and a few reborn with new attention.
Take a look at the songs used to create stations like Staind, Seether, Breaking Benjamin, Disturbed, Korn, Sevendust, Saliva and others. Just creating a station based on the group wasn't enough for me, I added most of the songs Pandora has for each artist on the station. It has been my experience that when a group releases their third album they have gone through significant changes. Seeding with a wide mix of their songs ensures the best chance to hear the full range of a bands musical talents.
If you would like to a specific group station created, just leave a comment and mention your favorite group. Of course if it's country music you are after, you are in the wrong profile! :)
Feel free to use my stations to make your own mix. Link to them, then create a "quick mix" selecting your favorite groups. Then sit back and enjoy a wide range of music.
