Not really a good thing.
People developed instrumental music in conjunction with singing, dancing, worship, celebration, festivals, parades, feasts competitions etc. For music to exist separately from those things is unheard of in some socieities. In some countries, like India, popular music doesn't really exist separately from movies (maybe that's changed some).
This whole Western norm of "you're the audience so you sit there and stare and us while we play music" is not too common, I think. Good thing or not, people often see music as part of something larger, including a video, dance, song, etc.
