Also, I strongly disagree about the name change -- "EDM" might sound stupid, but its widely accepted terminology, and you instantly know what the site does based on the name.
EDIT: Since you mentioned Spotify, an "Open in Spotify" link for each song would be killer so users can save songs they like for later (if this is in there and I missed it, woops). Either way it's in my bookmarks bar now (and you need a favicon!).
> "EDM" might sound stupid, but its widely accepted terminology
Sure, it's widely-accepted terminology in the US or by people who are disinterested enough to label all electronic music as "EDM". It's also starting to refer to a very 'American' style of dance music, so it probably will turn off a lot of people, especially those most involved/interested in electronic music.
Music genres are one of those identity-defining topics[1], so it's best to sidestep the whole issue if there's any doubt!
I would argue against "EDM" in the name not because it sounds stupid, but because it limits the point of reference to a very specific style of music in a worldwide music-playing web service.
The reason why "Spotify" and "Rdio" are such good names is because musically they are undefined by the service and defined by you; you can listen to almost any kind of music on them. Also I think it's better to avoid acronymns; that can be a little obscure. Don't limit yourself or your business to identity-defining topics. See: Amazon, Zappos, Google, Apple, etc.
