+## Abstract
+
+This NIP enables a way for users to share live statuses such as what music they are listening to, as well as what they are currently doing: work, play, out of office, etc.
+
+## Live Statuses
+
+A special event with `kind:30315` "User Status" is defined as an *optionally expiring* _parameterized replaceable event_, where the `d` tag represents the status type:
+
+For example:
+
+```js
+{
+  "kind": 30315,
+  "content": "Sign up for nostrasia!",
+  "tags": [
+    ["d", "general"],
+    ["r", "https://nostr.world"]
+  ],
+}
+
+{
+  "kind": 30315,
+  "content": "Intergalatic - Beastie Boys",
+  "tags": [
+    ["d", "music"],
+    ["r", "spotify:search:Intergalatic%20-%20Beastie%20Boys"],
+    ["expiration", "1692845589"]
+  ],
+}
+```
+
+Two common status types are defined: `general` and `music`. `general` represent general statuses: "Working", "Hiking", etc.
+
+`music` status events are for live streaming what you are currently listening to. The expiry of the `music` status should be when the track will stop playing.
+
+Any other status types can be used but they are not defined by this NIP.
+
+The status MAY include an `r`, `p`, `e` or `a` tag linking to a URL, profile, note, or parameterized replaceable event.
+
+# Client behavior
+
+Clients MAY display this next to the username on posts or profiles to provide live user status information.
+
+# Use Cases
+
+* Calendar nostr apps that update your general status when you're in a meeting
+* Nostr Nests that update your general status with a link to the nest when you join
+* Nostr music streaming services that update your music status when you're listening
+* Podcasting apps that update your music status when you're listening to a podcast, with a link for others to listen as well
+* Clients can use the system media player to update playing music status
