Quick – you’ve got a music file that someone (a collaborator, a client, a friend) needs to hear. How do you send it to them?

It seems countless Web entrepreneurs have new ways for sharing media – there are online Flash-based music editing applications, social networks, elaborate MySpace and Facebook killers. We’ve been impressed with some, like the rich player and commenting and fans on Soundcloud or the ability to create artist/band pages that really work on Bandcamp. (The latter, I do really want to spend more time with.)

But sometimes, these services are overkill. This week, I had to get some revised sound scores to a choreographer so he could have them in a rehearsal. I didn’t want to share them with my network of friends or let people remix them in Flash – I just needed to get them to him in the easiest way possible.

That’s where drop.io is just absolutely gorgeous and lovable. Using something else? This is probably better.
