🎸 🥁 Rockbot 🎤 🎧

A GPT-2 based lyrics generator fine-tuned on the writing styles of 16000 songs by 270 artists across MANY genres (not just rock).

Instructions: Type in a fake song title, pick an artist, click "Generate".

Most language models are imprecise and Rockbot is no exception. You may see NSFW lyrics unexpectedly. I have made no attempts to censor. Generated lyrics may be repetitive and/or incoherent at times, but hopefully you'll encounter something interesting or memorable.

Oh, and generation is resource intense and can be slow. I set governors on song length to keep generation time somewhat reasonable. You may adjust song length and other parameters on the left or check out Github to spin up your own Rockbot.

Just have fun.

Background

With the shutdown of Google Play Music I used Google's takeout function to gather the metadata from artists I've listened to over the past several years. I wanted to take advantage of this bounty to build something fun. I scraped the top 50 lyrics for artists I'd listened to at least once from Genius, then fine tuned GPT-2's 124M token model using the AITextGen framework after considerable post-processing. For more on generation, see here.
