To me, it's a matter of structure, more so semantics, but I wouldn't rule out that meaning is expressed through structure, or rather the position a word holds within the sentence.
Frequency adverbs occur inside the verb phrase if the verb is a form of BE. The reason being, and this is pure speculation at this point in time, is that BE, being copular, or rather a linking element that joins the subject with the participle ING, is not a verb, and so it cannot be modified by an adverb. So the adverb is placed after BE, inside the verb phrase: is always playing.
Just my thoughts.
