If you price this at $25, you'll lose that group of people that were looking to save money, (you could argue that at $25 it's still cheaper than a wedding planner).
Not every bride is foolish enough to think that everything will be perfect. The more money you have the more 'perfect' it can be. Those on a budget will opt for a $5 DJ that can get them as close to perfect as their money will allow.
That's exactly my point, when your competition isn't even anywhere in the neighborhood, you might as well raise your prices. A bride-to-be isn't going to see a $25 wedding DJ app as being expensive; she's going to see it as being 1/10th of what an actual wedding DJ would cause. You said people are only willing to pay for wedding-related services - well, this is replacing a wedding-related service, and you have to consider the competition when determining pricing.
And I don't think it's only wedding-related services that cost a lot. There are plenty of purchases associated with weddings (clothing, food, etc.) that are way overpriced.

They don't all have to be that foolish, there just has to be a big enough group of them that you have a solid customer base. In this situation, I think that's definitely the case.
It would also be good to have paid for content - like pre-chosen track listings, affiliate sales would be high for this too!
Pricing it at $25 would be a disaster. You can bet the barn on that.
