Well, whether it's in the title has relevance in regards what is meant by the artist. When it's just in the title it doesn't mean that the artist thinks it's a symphony. But if they describe it as a symphony then they consider it to be one (So I'm for instance not in the position of having to consider this song by The Verve you mentioned to be a symphony just because of the title).Whether it's in the title or the description makes no difference. There are objective musical criteria to define the genre. In this case, they are partly met, but not totally. As you wrote it's important that all criteria are met. Otherwise a string quartet would suddenly count as a symphony as well (meets all the criteria but one, which is the number of instruments). Of course these criteria have been adapted over time. A 1950 symphony is markedly different from, say, an early Haydn symphony. And yet both do meet all the relevant criteria which defines them as a symphony. And this album does not.
If the term album of epic music does not convince you it's probably difficult to find an appropriate term. (By the way, I think there are plenty of albums where all the tracks are not individual, but tightly woven together). Album of hybrid music is certainly not far off. If at all, the narrative (the life of a human being from birth to death) would put it closer to the 'symphonic poem' than to a symphony. But it's not that either.
But in the end, if you enjoy the music it's probably not particularly relevant to which musical genre it belongs. Whether symphony or hybrid album, if you dig the music that is all that counts.
Regarding the criteria... I guess that'd be getting more complicated to discuss I don't think every single criteria of a term needs to necessarily be met (no idea where I could've have said that).
It depends on how many are broken and how important they are.
Number of instruments can of course be a huge deal if only a handful of instruments required for the symphony term are there.
Well, despite all the terminology wars - happy to read that you have been enjoying Seven!
I also think it has way more gravitas than most of what Thomas wrote before (despite already being a crazy fanboy haha). I also found some of the FFF trailer parts a bit overbearing mainly because of the choir and the compression at the mastering stage.
