Set up alarm with fade-in, for graceful awakening
There are a lot of commands, which invokes your player at specified time. But I prefer not to jump from by bed, when alarm start to play. Instead, this script increases volume of mpd over time, which much more pleasant when you just woke up :)

Also ignoring "sshd" server is necessary since you should not kill ssh server processes.
