sort of compilation '70's, disappointing 2nd drive

This soundtrack sounds like a best-of (that is what it is, actually).
The titles are mostly well chosen for the film, and the replay with pleasure. Like many I discovered the Blue Swede group as well, and in passing I recommend their album Hooked on a feeling (it transpires the Beatles!)
I'm much more reserved on the 2nd disc, because the "heroic" theme comes back too often, and the rest is a little too boilerplate. At some tracks I forgot that music turned ...

NB: there is a version without the 2nd disc. If the price difference justified, rather than having only the music (sung) of the film.
