the evaluating means corrects the given evaluation value in accordance with a tempo of the content to be evaluated wherein a correction coefficient is determined so as not to decrease the evaluation value if the elapsed time is extended due to the tempo of the content being slow.

10. The replay apparatus according to claim 9, wherein:

the evaluating means gives an evaluation value indicating of a higher preference to a content which is replayed to the end and consecutively replayed again.

11. The replay apparatus according to claim 9, wherein:

the evaluating means gives an evaluation value indicating of lower preference to a content if replay frequency of the content exceeds a threshold value.

12. The replay apparatus according to claim 9, wherein:

the evaluating means gives an evaluation value indicating of a higher preference to a content if a newly stored content is replayed for the first time.

13. The replay apparatus according to claim 9, wherein:

the evaluating means gives an evaluation value indicating of a lower preference to a content if the content is replayed after a preset period of time has elapsed since the first replay.

14. A replay apparatus replaying a plurality of stored contents sequentially and including an evaluation button manually providing preference to respective contents, the replay apparatus comprising:

measuring means for measuring an elapsed time from a replay start time of a content to a time when the evaluation button is pressed; and
