Are we being censored in America?

I noticed quite some time ago that the lyrics of a Peter Gabriel song were being edited to cut out the phrase ”...see the doorways, of a thousand churches.” I may even have asked about it on this site. I can’t remember. Anyway, I know I mentioned it to people and no one really seemed concerned besides me. I’m fairly used to that.
But recently I was downloading some music to burn a disk for my mom, and one of them was an Edwin McCain song; “I’ll be”, I think is the name of it. Anyway, it’s kind of a nice, easy to sing along with type of sone, but a lyric had been cropped; “I’ll be – love suicide.” I didn’t realize until after I had downloaded and burned it. I went back and tried to get a different version, but they all have that phrase missing, and the resulting ediding job sounds horrible.
So I got to wondering; What other songs are being censored? Who is responsible for this? Whether or not you like the actual music, isn’t it some cause for alarm that music is being censored to not mention topics like religion and suicide? What else is on the taboo list, and who is making the list. Even more frightening, who has the clout to remove parts of songs from music stations across the country?
Am I just imagining things?
