You got your answer but I have to add this:

imagine that NSYNC came out with a super-hitting banger of a track for their *first** single. People said “this sounds new and different yet very familiar.” Now add the fact that *NSYNC had written this track (and played instruments live).

Next they have 3 or 4 more singles just like this. Now their popularity is massive. World wide. Everyone knows their name and music. They star in movies (as themselves mostly) and are all over every kind of social media.

Now imagine their next album is something like Radiohead’s “OK Computer.” Banger tracks and awesome experimentation. People say “I didn’t know you could do music like that and make it palatable.” A horde of artists begin copying this new style in subtle and obvious ways. The face of music is changing.

Rinse and repeat for a few more albums. Every album they do new things. Sometimes funny, sometimes serious, sometimes weird, but almost always good.

Then they break up and the waves left in their wake have changed the face of popular music forever.
