Are songs with profanity allowed? I wasn't considering doing anything offensive, it's just that every other hard rock song these days has the F-word once or twice.
Clever use of an aptly-timed sound effect can turn a PG-13 song into a PG song, so you could probably do something similar to turn an R-rated song into something more family-friendly.
Well, a warning doesn't hurt anyone, and lets those moralist people know what to download ;> ... To think there are some farkers out there who get offended by a simple mfing cuss word!
