Advice to listeners of metal, rock, rap, Goth, all kinds of devil-inspired "music." Stop it! Go cold-turkey for 21 days and see if your prayer life, mood, and mental and physical health isn't improved! It worked wonders for me. After an Ignatian retreat (to which Fr. Joe Pfeiffer dragged me me under protest!) I gathered all my CDs, tapes, records (Yes, I'm old!) and sorted the wheat from the chaff. Most was chaff. I went without for 21 days, after which time I consigned the chaff to the campfire. No, I didn't listen to Metallica or anything in that category, but came to realise that I was intellectually lax from listening to the popular tunes of my younger days, the late 60s through early 80s. What do I still listen to? Irish music, classical, folk music, marching bands, Catholic music, some bluegrass, Palestrina, chant, both Gregorian and eastern rite, music that has stood the test of time. Music has a way of 'sticking' in the mind and heart. Think! I didn't want to be found on my deathbed with "Get Down Tonight" going through my mind!
