Carkins,
A great contender in this space is TuneSmith and Rhyme Genie. TuneSmith offers more administration features than MasterWriter and also allows you to print chord sheets & lyrics.

It runs Rhyme Genie as a plug-in which is pretty much the mother of all rhyming dictionaries (300,000 entries, intelligent rhyme with plenty of compound rhymes, 50,000 song titles, syllable matching synonym…etc). They have a section online which compares the features to Rhymesaurus and MasterWriter:

The package costs $25 which is a lot less than MasterWriter.

Best,
Paul
