You say that, but other artists and labels will promote an album upwards of 2 years after it was released. It's kind of funny how the opinion has changed. Back in the day, fans would complain because they would drop one video right around the release date and then never release anything else. "You should put more promotion into the album, promote it longer, etc." Now, they drop a video 7 months after the albums and it's all "What's this nonsense? That album was sooo 7 months ago! On to the next one!"
