It's the little things that really make or break a system. For instance, earlier tonight a song came up on my playlist in Amarok. I realized the name was misspelled. I corrected the ID3 tag. I then went to the directory where the file was and renamed it. The song was still playing. Amarok noticed and rescanned my collection, updating its records of the new file name, and kept on playing the song without any interruption.
That is how a computer is supposed to behave. :-)
Half of that is Xine (it
Half of that is Xine (it probably had the entire song buffered, which kept it playing), half of that is Amarok using its incremental scanner to update its database. You may notice that your statistics for that song should have been kept intact too -- that would be due to something called AFT, or Amarok File Tracking. More information is available here: http://amarok.kde.org/wiki/AFT
Keep on rokin'!
