i did not let my kids put matisyahu songs on their mp3 players (back when it was my choice), but honestly, i have been very pained by many of the other albums from mainstream singers who should know better.
I know it’s an old discussion but i am just saying that while your comments toward Matisyahu’s music may be quite valid, it is not very different than much of the “frum” music so it probably shouldn’t be singled out. it needs to be a consistent message to our children and consistent hashkafos for ourselves. sick music from guys in a suit should probably be discouraged with the same level of disdain. (yes, i did hold back some of the other albums when i realized what they sounded like. just learned the lesson late)
