We're sorry. It's been a good run. Instant FM is no more.
We originally built Instant.fm in 2011 and stopped actively maintaining it shortly thereafter. The site was just a class project at Stanford, afterall. We would have loved to keep the site running forever, but alas, bit rot has finally claimed it.
The site broke several times over the years and we've always been able to apply an easy fix. This time, it broke and it wasn't so easy.
Feross built another site called Play that has similar (but not identical) functionality and it's actively maintained.
Go ahead and give Play a try!
