```csharp
public class DisconnectHandler : IRequestHandler<DisconnectCommand>
```
### PauseHandler
Handles the command to pause the currently playing track.
```csharp
public class PauseHandler : IRequestHandler<PauseCommand>
```
### PlayHandler
Handles the command to play a track or playlist.
```csharp
public class PlayHandler : IRequestHandler<PlayCommand>
```
### ResumeHandler
Handles the command to resume the currently paused track.
```csharp
public class ResumeHandler : IRequestHandler<ResumeCommand>
```
### SkipHandler
Handles the command to skip the currently playing track.

Handles incoming messages and processes commands or statistics requests.
```csharp
public class MessageReceivedHandler : INotificationHandler<MessageReceivedNotification>
```
