according to the writer : This seems to work with iTunes 8 and 9, although you'll need to redo the patch after upgrading.
Open a Terminal and type the following
cd /Applications/iTunes.app/Contents/MacOS
sudo mv iTunes iTunesX
sudo curl http://www.cs.umd.edu/~dmonner/iTunes -O
sudo chmod uog+x iTunes enter code here

import sys, os, subprocess

blocker = ""
apps = ["Spotify", "Songbird"]
ps = subprocess.Popen("/bin/ps -x", shell=True, stdout=subprocess.PIPE)
for line in ps.stdout.read().split("\n"):
for app in apps:
if app in line:
launch = False
blocker = app
ps.stdout.close()
if launch :
os.spawnvp(os.P_WAIT, '/Applications/iTunes.app/Contents/MacOS/iTunesX', sys.argv)
else :
print "Not launching iTunes while %s is running." % blocker
