Yes, because I'm targeting YouTube. I ignored it until they put into place their system for turning down loud content, and picked -13dbFS for their 'standard'. That's not particularly good by audiophile standards but it's achievable, car-friendly, and you can get some crest factor out of it while it still sounds pretty 'fullbodied'.
I revised 'Righteous' to help me target this. I hope there's some wiggle room in the spec and they don't just straight up process everything to be EXACTLY -13 dbFS because it'd be nice to be able to put out stuff that's the right density and have it play back unaltered… but the farther you depart from that, the more they'll change your output. If you're hotter, you'll get turned down (arguably less damaging!) and if you're under their loudness window you get crappy limiting. At least I'm given to understand Spotify is doing this and I've seen reports that YouTube is also doing it.
Can't speak for Spotify but there are indeed loudness targets and YouTube's was -13 dbFS last I looked. Know your playback environment. :/
It is 'stupid loud' mastering that created this situation, but it ended up affecting everybody 'cos the techies have a vested interest in homogenized output levels. Gotta enable seamless autoplay for advertising purposes. Can't have anything breaking the flow, now can we?
