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. :-)
