Not if you're using an ad-blocker.
Perhaps the reason you're using an ad-blocker is because you don't want to be tracked, and the only way to do that is to block ads completely. I get it. But you're also using up Spotify's bandwidth and licensing fees (which in turn allow music to be created in the first place), without providing anything in return.
This is only possible because paying and ad-watching customers are subsidizing your behavior. It is the definition of freeloading.
The issue isn't one of arbitrary code execution. Lets not be hypocrites.
AdBlock Plus has over 200 million installs on the desktop alone. Are you going to tell me that those 200+ million users of AdBlock Plus are concerned with arbitrary code execution? What percentage of those users do even know what that even means?
Between 10% and 20% of Internet users are using ad-blockers. Lets do an imagination exercise and say that Spotify would only serve images for ads. How many of those 10 to 20% of Internet users would whitelist Spotify?
"None" would be my guess.

I use adblockers to protect myself against malicious content masquerading as ads, which both the ad delivery networks and content platforms have proven unwilling or unable to address to an acceptable extent.
If you want to boycott Spotify for endangering people's computers, go ahead. Heck, if you want to attempt to use Spotify with an ad-blocker, go ahead. I don't feel morally comfortable using ad-blockers, but I won't fault others for using them.
You do not get to use Spotify's free tier, block their only potential revenue stream for that tier, and then turn around and cry fowl when Spotify notices and bans you.
I have this problem with websites, apps, social networks, etc. as well. I don't want to be tracked, retargeted and so on. Not because I think ads will influence me or anything but its about my trust in those companies and how they protect my data. When my data gets leaked because they are inadequate at security I don't get money back. I get a message saying "We take your privacy seriously"... And that data can then be used in various other ways to harm me.
Also I'm very pissed off with people who say freeloading. It's not freeloading. I pay with my time to watch or listen to your stupid ad. I should not also pay with my personal data. An ad is just an ad it should not have evolved to the monstrosity of tracking you.
It has evolved in the same way copyright has until we find a way to kill both of them as they are not needed in our world.
