best movie soundtrack album

[cdxx]

i searched for soundtrack but didn't find any previous threads on this. what's the best film soundtrack in your opinion?

btw, no fair using Dark Side of the Moon as the soundtrack for wizzard of oz, as it wasn't the original.

for me, it's soundtrack to Reservoir Dogs and Queen's soundtrack for the Highlander.

edit : also probably should stick to movies, rather than tv series.
