Sorry, I did not get the memo. The iTunes support site says: "Music and music videos available in iTunes Plus are indicated as such on the album or video page or track list." But I have not been able to see any indication on any music I have been looking at. Searches for "iTunes Plus" yield no good info on the topic. So, I am wondering if everything is iTunes Plus or if none of the music I am looking at is available in iTunes Plus. Thanks.
