I do not remember if I have posted this before, but I have been downloading some music from the AAJ site.
It is mostly newish, modern jazz artists, offering a free DL to sample their music. These DLs are full songs, not just samples and they have about thirty or forty pages, each with eight or ten DLs, one song at a time, from one artist at a time, but you can get a picture of where modern new jazz is going.
You will have to set up an account with a valid email to download "The Song Of The Day," but it is worth it and the exploration of a couple of years past is the real value.
I recommend that you remane your downloads immediately (they make it easy with large text to copy and paste), because they come with a server designation as the filename, which totally sucks. Some songs include extensive metadata to identify the music in a player, but many do not.
They offer a small "listen" panel (it's free to listen without signing up) and in seconds you can decide if you might ever like the music or you can just browse and see what is new out there.
All About Jazz is the site ...
https://www.allaboutjazz.com/Just set up and account, login, hit the "Explore" button, scroll down to "Song Of The Day" and choose your free music You can download gigs of free jazz on the spot, all MP3, of course, but it is a great sampling from each artist.
There is no limit as with other free sites like Freegal and such, limited to five or ten DLs per week - stupid!
I hope a few of you get some pleasure from this site as I have over the years.
The daily free song is only one aspect of this site, though. It is really an ongoing news source for jazz artists worldwide.
