I only ask this because I know music rights are what is keeping Cold Case, a show still running, from DVD. I am getting into the new WB series "Supernatural". However, in the two episodes thus far, there has been a number of classic rock songs from Foreigner, AC/DC and Rush played (it's established that the older brother Dean is a fan of classic rock). Considering the prevalence of TV-DVD's these days, are Warner smart enough to go ahead and clear out music rights for DVD as soon as the episode is produced nowadays, or will they make another mistake ala Cold Case by jeopardizing DVD releases by not making the assumption the show would get enough of a following that would buy the show? Since it's 2005 and it's a 1 hr WB series (since almost all of the WB shows are on DVD), are Warner taking the right measures and clearing the songs or are they setting us up for another WKRP/Wonder Years/Cold Case?
