The configured medium of claim 63 , wherein the process determines at least one of the following results: a frequency of playing artists in a given genre has changed in the same direction in both datasets; a frequency of playing videos or movies in a given genre has changed in the same direction in both datasets; a frequency of playing games in a given genre has changed in the same direction in both datasets; a frequency of playing a digital good in a given genre has changed in the same direction in both datasets; wherein “changed in the same direction in both datasets” means either increased in both datasets or else decreased in both datasets.
65. The configured medium of claim 63 , wherein the process determines at least one of the following results: a frequency of playing a given artist has changed in the same direction in both datasets; a frequency of playing a given video or a given movie has changed in the same direction in both datasets; a frequency of playing a given game has changed in the same direction in both datasets; a frequency of playing a given group of digital goods has changed in the same direction in both datasets; wherein “changed in the same direction in both datasets” means either increased in both datasets or else decreased in both datasets.
66. The configured medium of claim 63 , wherein the process automatically compares a first portion of the first dataset with a second portion of the second dataset, a portion of a dataset being less than the entire dataset, and each compared portion is specified by specifying at least one of the following: a playlist; a genre; an artist; a category; a date range.
67. The configured medium of claim 63 , wherein the process automatically compares a first portion of the first dataset with a second portion of the second dataset, a portion of a dataset being less than the entire dataset, and each compared portion is specified by specifying at least a Boolean combination of two or more of the following: playlist, genre, artist, category, date(s), play frequency, play count.
68. The configured medium of claim 63 , wherein the process further comprises automatically comparing at least a portion of the first dataset with at least respective portions of additional datasets in a group of datasets, the second dataset being a member of the group of datasets.
69. The configured medium of claim 63 , wherein the process determines at least the following shared recommendable goods presence result: at least a specified percent of library entries in one dataset support a recommendation of library entry(ies) in the other dataset under an automated recommendation system, wherein the specified percent is a predetermined percent.
70. The configured medium of claim 63 , wherein the process determines at least the following shared recommendable goods presence result: at least a specified percent of library entries in one dataset support a recommendation of library entry(ies) in the other dataset under an automated recommendation system, wherein the specified percent is determined at least in part by comparing at least a portion of the first dataset with at least a portion of the second dataset.
71. The configured medium of claim 63 , wherein the process determines at least the following shared recommendable goods presence result: at least a specified number of library entries in one dataset support a recommendation of library entry(ies) in the other dataset under an automated recommendation system, wherein the specified number is a predetermined number.
72. The configured medium of claim 63 , wherein the process determines at least the following shared recommendable goods presence result: at least a specified number of library entries in one dataset support a recommendation of library entry(ies) in the other dataset under an automated recommendation system, wherein the specified number is determined at least in part by comparing at least a portion of the first dataset with at least a portion of the second dataset.
