Seriously, while I think some people might dismiss your comment as snark, I genuinely was interested in this service, but am unwilling to create an account just to get a sample. Sites need to realize that "creating an account", while it appears as simple as supplying a few bits of information, anyone that cares about their time or security will find a few snags.
First, the email address. I don't give my email address away without thought as to whether this service will contact me in the future, how often, and about what. If I'm just trying to get an idea what you offer, I don't want to have to worry about you abusing that address in the future. My inbox is busy enough, thank you, I don't want to have to deal with you later if I've decided I'm not interested.
Second, the password. When linked to a global identifier like an email address, I'm stuck with the choice of using an easily remembered password or password template that I reserve for low interest sites that the accounts don't really matter on and the reduced security this entails, or coming up with a unique secure password (which either entails my trying to be random or a tool).
Now, I could generate a fictitious email and password just to try out your site (because I'm sure as hell not going to go through the effort of making a real separate email for you), but that entails me making a random email that isn't already used (what do you want to bet foo@example.com is already taken, or that domain is barred because they use it in testing?), and I don't want to have to think about that, I'm trying to get a quick idea about your service.
So, to site developers who gate examples of their service too aggressively, keep in mind every time I'm mildly interested in your service and you gate more info with a free account form, I groan internally. Of the mild interest I felt, and the feeling that made me groan inside, which do you think wins in the end?
I'm not telling a random internet service for no reason my proper first name, my age or my gender. I can see that there's maybe a reason for age and gender when suggesting music (even though it should be optional nonetheless), but my first name? Are you going to suggest me songs where people chant my name or something?
And because they insist on this ridiculous requirement of entering my first name, it also just becomes much less credible that they actually need my age and gender, and are not just collecting that to sell it away.
Well worth the minor hassle in setting it up, and you get an indication about which site leaked your password or was hacked. I use thunderbird, which even lets me type a from address for emails to make this more useful.
Although, the fact that there are popular tools available to work around the extra cognitive load imposed with account creation and tracking is a very good sign that a free account is much more of an impediment to the general person than these sites seem to realize.
Also, it doesn't affect the fact I still don't want to give away my email address before I've decided a service is worth having an account for.
It's a shame, because I am interested in seeing what the service is like. The problem is that my interest is part driven by wondering how similar it is to my current technique (put on my "Glitch Mob", "Zack Hemsey" or "Carpener Brut" stations on Pandora), wihch means I'm interested if it's slightly better, because I'm not unhappy now. I am at the same time very likely to use their service if it's good, but unlikely to jump through hoops to find out, since I have a solution that to my knowledge works sufficiently, and I've even decided it's worth paying Pandora for. Not exactly the type of customer they want to keep from seeing their service in action.
That link gets you straight to music.
