No. It still would have been huge but Mike‘s videos became not only a staple in his career but became an art form he would use to expand on his music. Like I said Thriller still would have been huge and have lots of praise. Thriller itself was very much ahead of its time and didn’t sound like anything else at that time. The songs themselves are legendary and with that amazing Quincy Jones touch. But the music videos brought the album to a new level that hadn’t even existed prior and influenced pop culture overall.
