+**Instructions:** Type in a fake song title, pick an artist, click "Generate".  At the expense of time, you may adjust song length or other parameters on the left.
 
-Note: Due to the nature of language models, lyrics bleed across artists and you may see NSFW lyrics unexpectedly (e.g., from The Beatles), especially if you change the configuration to allow more entropy. I have made no attempt to censor lyrics whatsoever.

-Finally, these lyrics are computer generated. Not all of these will be non-repetitive and/or coherent. Just have fun.
+Oh, and generation is resource intense and can be slow...
