Substandard recordings advice

The album I am currently finishing up was professionally recorded with professional musicians. It will be professionally mixed and mastered.

All my previous releases sound like ass in comparison. I have 49 monthly listeners on Spotify. I have about 130 tracks on Spotify. Only 3 of which have more than 1000 plays. Im tempted to scrub them all (except those three) and only keep the tracks which sound professionally recorded.

Does this even matter?

I feel the same way about the majority of my YouTube videos, like I should scrub all of the substand videos and only keep the better ones.

(If you are really curious, search my user name on Spotify or YouTube to find out what Im talking about.)

So do I scrub that substandard material or just not sweat it?
