Do you need the song to tell you to get shit done? Isn’t listening to that just putting it back further?
Usually I open soundcloud.com and have music from there running in the background. No specific songs I regularly or specifically for this I come back to. I do have my likes, shares, and follows though, if the feed is unfitting.
I wouldn’t use it.
Seems to me like free plan is what browsers natively support anyway. (Scam site blacklist. I highly suspect they use the same. They can’t compete with the one Google hosts and all major browsers integrate.)
And instead of paying 15 usd per month, Windows defender is a well funded, well established, well trusted solution.
There’s no practical gain in blockage before download. Windows defender scans upon and after download, before execution.
