If you are Catholic, it would bother you...if your Protestant, not so much. If you're REALLY into good music, and can play it(well), churches are as good as a place as any.
BTW, did you know that the Church(Catholic, at the time), banned Bach's music from being played in their churches, or rituals....Bach began stacking chords in FORTHS, and the church thought it was of the devil!

You can now hear Bach in churches. Ah, the power of great music!
