If the re-mastered works aren't up yet, I'd assume they won't be. There's really no difference to the normal listener. At my station, when someone has re-mastered work, we usually don't replace the songs, unless it's a different mix, then we just overwrite the existing song. We did this for Pearl Jam, and nobody knew the difference. Even on FM, remastered material isn't a big deal. Most people would need to hear both versions of the song to tell anykind of difference. IMO, for a station that plays classic rock (Beatles), having that "old time produced sound" is part of the format.
