"Take me to church" is a song by Irish soloist Hozier. It's not a bad song as such, but it's certainly not about going to church!
Hozier wrote the song after a break up with a girlfriend and it is therefore both a love song and a song about contemplating sin. Hozier also says that he was inspired by the late Christopher Hitchens, an atheist song writer, so there is possibly some non-Christian elements to the song.
The lyrics are more strange than blasphemous to be honest, but if you are a religious person I really don't think this song will appeal to you.
However, some people love it apparently, as it was the most streamed track globally on Spotify in 2014.
