Please enjoy jwz mixtape 187.
Does anyone besides jwz make these kinds of mixtapes? Can anyone recommend anything?
Depends on what you mean by "these kinds".
For monthly mixtapes of fresh new music, try Swell Tone Music and Turntable Kitchen.
If you mean music video art, you can try NOWNESS: Music, Art & Design, Electronic Music, etc. They have all sorts of channels!
You can also try drinking from the firehose of the Internet Music Video Database: New Releases and Channels. IMVDb is more of a moderated (but incomplete) collection of music videos of all genres. And their collections are more like feeds and less like mixtapes.
Reddit's /r/listentothis has an annual best-of for videos: eg, 2016, 2014, 2013. (If memory serves, some of them aren't acutally music videos.)
There are not nearly as many regular genre-moderated video mixtapes on the web as there are audio-only mixtapes. You should start posting some!
Thanks for the suggestions, I'll be checking those out. I'm afraid I'm not nearly cool enough to be a musical maven myself, alas.
