One of the best and jingling .ly sites, a music search engine song.ly, semi-tuned for Twitter, was just sold for $50,000 via Flippa.
The site had also developed an API and a Firefox add-on. Despite low ranking at Alexa, considering all the perks, it is questionable whether the actual transfer will happen after this auction.
Though, the proposed price is aligned with that suggested by BIZinformation: 127,410.95 LYD or 99,711.18 USD.

http://onmusic.me/ seems to offer similar services, so song.ly sounds so much better.
