Dear users. I have been running this service for 15 months with over 1.7 million songs processed. For the last few months, credits and donations have not allowed me to cover server costs. This is why I am trying out a new free credits model, switching from 7/week to 2/day. This allows for more free use (14 per week) but hopefully will incite people who can afford it to purchase credits and keep this site afloat. Cheers.
