Hey Borland, you ever notice how starting an album feels like starting a new project—there’s a ritual, a flow that just needs to be respected? I’m thinking about building a music player that guarantees you can’t skip out mid‑track or mid‑album. What’s the cleanest way to structure that so the code stays as reverent to the artist’s intent as I am to the vinyl?
Borland Borland
Borland You can treat the player as a very simple state machine – a few clear states and a rule that moves you forward, never backward. 1. **Define the domain objects** – Album, Track, PlaybackSession. 2. **Make PlaybackSession immutable** once it starts: store the album, current track index, and a flag that tells whether skipping is allowed. 3. **Expose only one public method** to start the next track: `next()` or `finishTrack()`. Inside it, check the flag; if skipping is disabled, ignore the call. 4. **Keep the UI or API read‑only**: expose `currentTrack()` and `currentAlbum()` but never let the caller set the track index. 5. **Handle the end of an album** by setting the session to a finished state; after that you either ask the user to start a new session or stop playback. Because the session is immutable, there’s no chance to slip in a stray assignment that lets a user jump ahead. The only way to change the track is by calling the controlled method, so the artist’s intent stays intact. Keep the logic in a small service layer and test each state transition; that’s the cleanest, most reverent way to code it.

Nice breakdown, Borland, that’s almost like a track list for a session. I like the idea of an immutable PlaybackSession—keeps the flow unbroken, just like a classic vinyl pressing. Remember to add a little buffer for those pesky gaps between tracks, like the vinyl’s natural pause, so you don’t feel like you’re skipping. Keep it clean, and don’t let the user hit ‘next’ until the whole track finishes, or it’s like cueing up a single and dropping it in the middle— sacrilege, really.

That’s the right mindset. Add a tiny pause flag inside the session, fire it once the audio buffer drains, and only then enable the “next” button. If you keep the buffer logic in the same service that controls the state, you’ll have one place that knows the rules. A quick unit test for the pause transition keeps the edge cases out of your day‑to‑day code. Then the player feels like a proper vinyl run‑through, no accidental cueing.

Got it, you’re basically turning the player into a reverent ritual. That pause flag is the moment between the needle and the groove, the sacred silence. Add a unit test that checks the flag flips only after the buffer drains, and you’ll never see a skipped track again. Keep the service as the guardian of the album’s sanctity. That’s the kind of design that makes a digital player feel like a vinyl ceremony.

Sounds solid—just keep that flag in the same place where you handle the buffer callback. A small test that asserts the flag stays false until the callback fires will seal the deal. Then your player will feel as if it’s following a vinyl setlist, no accidental jumps.

Sounds like a perfect ritual, Borland. Keep that flag close to the buffer callback, test it hard, and your player will behave like a vinyl run‑through—no surprise skips, just pure album flow.

Glad you’re on board—keep it tight, keep the tests tight, and the player will honor every track.
