Changes to Music Poll. Yea or Nay? (Patreon)

Greetings Patrons. Something has been brought to my attention and I would like to address it with everyone. I was wondering if we should create a small rule for the weekly Music Poll to balance out the artists that win each week. For example, PTX (Superfruit, and their individual members solo stuff) will probably win every weeks poll each time they are suggested due to the high amount of PTX supporters here on Patreon. I love PTX and their music and have no problem doing it each week, but in the interest of keeping some balance and encouraging the underdog artists, how do you feel about the following.

The winner of the weekly poll cannot win again in the following week. So for example, if PTX wins this week, then I will not put PTX suggestions on the following Poll, however, PTX can return to poll in the week after that. So they could still win every second week. Is this something I should do to keep more of a variety on the poll or should I just let the poll winner be whoever wins, even if it's the same artist every week?
