Yes, it's usually done via nice/renice commands:
renice -n -10 -p `pgrep mpd`
You can tune it's priority up to -20 (most real-time priority).
I'd suggest looking at load-average it generates ("top" shows it, at the
top)) first.
After running mpd for 15 minutes or so, if any of the three (5/10/15)
will go above number of physical CPU cores you have (and that's
probably the case if you see full load at any given time), tuning it's
priority up will make the rest of the system extremely sluggish, since
mpd won't let any other process to execute and just doing "ls" may take
ages, not to mention whole X operation...
