Web API rate limit

[Nizumzen]

I want to build a website based heavily on the Spotify API, but I'm a little bit concerned about the rate-limiting. Obviously, it won't be a problem initially, but if my website gains in popularity, I end up risking hitting the rate limit.

Does Spotify offer a way to increase the rate-limiting? I don't mind paying for it, but I want to make sure that it won't become a problem further down the line.

Thanks.
