I have seen a few notable similarities. 1. The titles of these albums are the last words in the opening track, and both are related to time, but in opposite ways: Somewhere in Time -> 1. Caught Somewhere in Time ("Time is always on my side"). The Final Frontier -> 1. Satellite 15....The Final Frontier ("For I've very little time"). 2. The texts in the booklets have the same fonts. 3. I noticed that the autobiographical lyrics of Wasted Years (which stand still with touring/life, and urge to enjoy these years) could fit on The Final Frontier, on which some lyrics also (optimistically) deal with being satisfied about life without any regrets. Do you guys see some more relations between these albums?
