I haven’t gotten this feature in Facebook yet, but I’m intrigued. Yes, it’s the same basic idea of turntable.fm, but like with so many other products that Facebook rips off and bakes into their product, it has the massive advantage of having all your friends right there, rather than having to convince people to sign on to a new service.
I loved turntable.fm, but found it to require a pretty good amount of time and attention to DJ (not really something you can do in the background while you work). The “Listen Along” function means that if a friend is just listening to a single album, you can listen along to that. None of having to find and queue up songs, which, granted, is a lot of fun, but only if you have the time for it.
Finally, this is an even bigger plus for Spotify and other services that are plugged into Facebook not only in that it’ll make people listen more, but there will likely be a lot more people like me who turn the sharing to Facebook back on. It’s not just annoying now: it’s actually fun.
