If You were going to upgrade to Hype Pro solely for your lyrics video projects, then yes Motion would be your app of choice IMO; and do not be deceived by Motion’s price - it is a powerhouse in an easy to use interface. I am an Adobe Creative Cloud member - After Effects is part of the package - I prefer Motion.
Hype Pro is a great upgrade for projects that are HTML5 based. If your pocketbook allows it is an excellent value and recommended.
