If you are copying from a *nix filesystem to a Windows filesystem
(which is implied by your use of mountsmbfs) then the timestamps may
not be matching since Windows uses a 2-second granularity.

Try using the 'stat' command on a file in the source and destination:

  stat "/music/Reggae/Damon Marly/01 - Confrontation.mp3"
  stat "/musicbackup/Damon Marly/01 - Confrontation.mp3"

The "Modify" times should be the same, down to the second.

If they differ by one second, use  --modify-window=1  and that will
allow rsync to match the timestamps.

(Wayne - the "copies every file" entry in the FAQ should also mention
this problem with Windows timestamps.  Even though it may not be "every
file", it may seem like it...)
