JohnJohnJohn,
I always found the idea behind MasterWriter's Songuard interesting but wonder how the service is different than uploading a song to any other online storage (iCloud, SoundCloud, Amazon…). As soon as you upload a file you pretty much established a 'date of creation' protection - or am I mistaken?

My main issue is that MasterWriter makes it not very intuitive to maintain song splits easily or even use pseudonyms. That is certainly something that TuneSmith excels in.

I agree that you can pretty much ignore most of the rhymes that Rhyme Genie offers. I pretty much stick with the intelligent rhyme and the family rhyme (which was actually conceptualized years ago in one of Pat Pattison's book if I am not mistaken).

The registration procedure is a little odd but what I like about it is that you can use the same serial number to activate Rhyme Genie on your iPad or iPhone as well as your computer. There might be an iPad version of MasterWriter in the works but so far a MasterWriter App has not materialized.

Best,
Paul
