The troubled online ad-supported music startup SpiralFrog has raised another $2 million. Not that this will help in any major way for the site to break through with consumers, but would certainly help as operational capital, something it has been looking for since earlier this year. The money was raised through a private placement of its senior secured notes. More in release. For a list of who all bought shares in this placement, see this series of SEC filings done on Friday.
