LinkBox: The AI music player you own forever — no subscription

Hey Product Hunt 👋 I built LinkBox because I was tired of two things: renting every piece of software I use, and watching "smart" music apps get worse the bigger my library got. My collection had grown past 70,000 tracks and links, and every player I tried either choked on it, buried the good features behind a subscription, or basically turned my own music into someone else's account that I had to keep paying to access. I didn't want a service. I wanted a tool I actually owned. So I spent the last three months building one. LinkBox is a fast desktop player with AI wired into every layer — ask it for a vibe and it builds the playlist, the shuffle genuinely learns what you love, and the library quietly cleans itself (dead links and tracks you're done with just slip out of sight). You can run the AI locally or in the cloud, recolor and rearrange the whole interface, and it stays snappy even at 70k+ tracks. The part I care about most: it's a one-time $9.99. No subscription, no accounts, nothing held hostage — and updates are free for life. Software you own, not rent. Would love your honest feedback, and I'll be hanging around all day to answer anything. 🙏
