Music composition and playback software...FREE!

For all you songwriters out there, this program will make your music notation for songwriting so much easier.  It is called MuseScore and it is FREE.  I personally downloaded it and am also using it in many of the latest compositions I am working on.  The beauty of it is that, like many of the other paid music notation software programs, this will also let you play back any note combination you input in the staff.  So far so good for this one.  Highly recommended.
