I have explicit filters turned off, I don't want censored songs. However, some songs have clean or radio versions that I prefer. For example, "F*ckin Perfect" by P!nk, or "Fake it" by Seether, where I would prefer the radio version. But when I turn off the explicit filters, I get the studio version, and while I don't mind cursing, those two (for example) are just a bit too much and the radio version is just better (in my opinion).
I wish Pandora would allow me to choose which version of a song I hear if there is more than one to choose from.
