Just noticed this today, not sure how long it's been around.
That Blasts From The Past one seems like a good idea, noticed Spotify have started doing this on the front page, but it's about time some of these recommendations mined some of my old listening habits. It's great when you get reminded of an old release you really liked but forgot about.
It's good that they're starting to do more with the data, I wonder if they'll really put the investment into making some really clever stuff, particularly as most other websites have overtaken them in so many regards.
Probably too little too late, but still nice that they're trying.
