There's drag and drop support in streamtuner2 [since 2.1.7](technote/e469da47ac9778f590c46d52feb17e11787848e0), primarily meant for exporting individual stations into .XSPF or .PLS files, or dragging them into audio players.
There is also support for proper XDND payloads. However most BSD/Linux desktop applications support little more than `STRING` or `text/uri-list` file dragging. There's no standardization in or beyond that. Which is because nobody bothers to document anything. So as exception to the rule:
| drag target MIME type | info id | content / payload | actions |

- The example payloads are abstracted here.
- The info ids are just Gtk-internal.
- Ordering doesn't reflect priority handling.

As said, only <kbd>text/uri-list</kbd> is used in practice. It doesn't allow actual streaming URLs being transferred. Instead streamtuner2 has to create temporary export files. And since this dumb approach doesn't allow any content-negotation, a preconfigured default playlist format will be used for temp files. (Defaults to XSPF for crashing Rhythmbox.)
Alternatively there's <kbd>text/iri-list</kbd> now (yes, why not go with the century?) and <kbd>url/direct</kbd> to get a direct streaming URL/IRL.
