Song featured: Heroes Tonight by Janji and Johnning (NCS).

For legal reasons this is a joke.

CLI for local LLMs to roast your music taste.

Why the name?

Short for track-roast.

Another way you can think of it is: "trust me bro my music taste is totally good".

Who is this not for?

Those who cannot tolerate humour ranging from light-hearted banter to absolute emotional damage.

If you do not want the LLM to be too mean, there is a scale of "how much of a jerk the LLM can be". This is mentioned below

Features

• Reads .lrc when found in the same directory as audio file(s).
• Semantically infer genre/sub-genre (best effort basis) via LLM
• Local metadata cache for parsed songs

No CGO Sqlite database, defaults to where it makes sense on your platform

• Read file codec, title, description, metadata

• Choose between distinct personas, including:

  • brainrot: A chaotic, hyperactive stream of raw Unicode emojis and stunted streamer slang. Decries your "L codec choices" with zero aura.
  • detective: A Sherlock Holmes-inspired sleuth treating your lossy files and neglected metadata as an active crime scene.
  • elitist: A snobby 90s record-store clerk who despises the mainstream and sneers at digital peasant compression profiles.
  • hater: A relentlessly toxic internet troll providing pure, bad-faith hostility regardless of configurations.
  • influencer: A cringe-inducing content creator plagued by toxic enthusiasm, over-inflated vocal fry, and desperate engagement metrics.
  • nerd: A pedantic, socially awkward tech nerd starting sentences with "Erm, actually..." to viciously analyse your compressed frequency cutoff maps.
  • normie: A delusional TikTok-era middle-schooler defending generic radio pop charts using shallow arguments.
  • parent: A traditional immigrant Asian parent comparing your lazy file selection directly to your flawless cousin Timmy (who gets straight A+). Wields the slipper (if yk yk).
  • pianist: An arrogant classical conservatory elite appalled by lossy shortcuts that clip essential musical harmonics.
  • posh: A passive-aggressive British aristocrat deploying devastatingly polite backhanded insults over high tea regarding your low-budget container formats.
  • sarcastic: A hyper-sassy, cynical lady dispensing raw, zero-filter side-eye directly at your audio storage compression standards.
  • spitter: A ferocious battle rapper delivering fast-paced cadences in snappy 8-12 word bars, targeting your low-bitrate MP3 choices.
  • therapist: A concerned professional diagnosing your fragile psychological state based on your severe lack of metadata care.

• Set how much of a jerk the LLM persona can be. On a scale from 1 to 5, defaults to 3. 1 is lowest, 5 is highest.

Note: Hater will still be a hater even you set jerk value to 1.

• Set whether profanities are allowed in the outputs. Defaults to false.

Most models have safety nets baked into their system prompts, if you do want this you are very much on your own.
