Liturgy of the Hours

I love the Liturgy of the Hours now that I can turn on the I-pad, click on the apps, turn off the light and pray along in the dark and go to sleep. No more page turning. The apps also play hymns and I can hum along. Previously, even if I knew the melody, I could not sing, because I sing off key. The only melody that I know for sure is Joyful, Joyful. So I sang everything to Joyful, Joyful although I hate Joyful, Joyful.
