Each day I generally set MC playing from the current "next track" in a very long playlist and at the end of each "listening session" use the stop after the current track option before closing MC down. Yesterday other than to set MC playing and then later in the day telling it to stop playing after the current track so that I could close MC down I spent most of the day at least 4 feet away from my PC. This morning I decided to do some checking to see what MC had been doing and discovered that it had "bookmarked" 33 tracks - see attachment 1.
So I did some investigating and discovered that despite the wiki Bookmarking stating stating:- "If the playback position was less than 60 seconds into the file, then the bookmark is cleared (unless it was a DVD)"; 5 of the tracks it had bookmarked had Durations that were less than 60 seconds.
The other "commonality" was that the tracks it had decided to bookmark had durations below 2:25. However this morning it decided to bookmark a track that had a duration of 2:37.
I decided to replay the track highlighted in attachment 1 to see if I could spot any visual clues that could explain why MC had decided to bookmark it. Attachment 2 quite clearly shows that the track was still playing at a point 1:47 into it's 1:48 duration but as Attachment 3 shows MC had decided to Bookmark it once again but with a value of 102546, not the 102475 original value.
Thanks to the Tag Window I was able to check to see if there were any tracks with durations of less than 2:38, in the batch of tracks it had played yesterday, it had not tagged. Every track of a duration of 2 minutes or less had been tagged, but i did find some tracks that had a duration of less than 2:37 that had not been bookmarked.
I accept that unless I switch "Use Bookmarking" on those bookmarks will never get acted on, but I am probably not the only user who
can do without MC doing things it shouldn't be doing!
