I tried to make it clear that my statement was predicated on whether or not you've listened to it much. Not because it's impossible to be correct in your appraisal of something with little exposure, but the weight I give your opinion is a function of both your exposure to the topic, and the variation the topic exhibits. I think TAL has quite a bit of variation in message, topic and to a lesser degree quality. I don't think limited exposure will, in the average case, produce very accurate opinions about it. Of course, I don't truly know how much exposure you've had (which I also tried to allude to by using "I can't imagine," which is meant to be left open for correction).
