Well, if "belie" means "fail to fulfil or fail to justify", then "the quality of the music seems to belie the criticism" would mean "the quality of the music seems to fail to justify the criticism."
It is a bit weird. If it has said "the quality of the music seems to fail to justify the acclaim it received", it would be fine.
What do you think?
Context:
belie
Fail to fulfil or justify (a claim or expectation):
the quality of the music seems to
belie the criticism
