Is releasing title song and album digitally before the official MV a good idea?

Typically we get MV and Title song with digital album release on the same day and at the same time.

But is it a good idea to release the Title song and digital album one day (or even one week) before the MV?

So basically you hear the song(s) first before the MV.

And the MV teasers keeps going.

Do you think this idea will provide the time for the listeners to make a fairer judgement on the song(s)?

So that the listeners can make a separate fairer judgment on the MV?

Or is there no real benefit in doing that so why even bother?

opinions?
