AOL appears to be in the process of shuttering its AOL Music properties today, April 26th. A series of tweets, some of which have since been pulled, have specified that the staff were laid off/fired earlier today.
Sites impacted by the decision include Spinner.com, Noisecreep.com and the Music.AOL.com portals, among others. A collection of tweets from some of the staff who lost their jobs can be found over at Techcrunch.com.
