One possible way to solve the legal troubles is to just remove any references to the product name 'Shazam'. You could title the blog post "Algorithm in Java that identifies music similar to other commercial products" (too long.. but use your imagination)

That wouldn't do a thing. Patents cover the code, not the names. (Well, the "embodiment", but since all there is here is code, it is clearly covering the code.) That would only help a trademark infringement, and there isn't one here.

Ah.. good point.
