Ambient-relaxing website

The project is about the creation of a simple, minimal website for listening to sounds and relaxing, for example during work. The aim is to create a homepage where people can choose the most relaxing sound they prefer between a set of predefined (but customizable) minimal icons (representing the sound they symbolize). Clicking on the icon, people can listen to its sound, in loop-mode, deciding the volume and whether to combine the sound with an other sound. At the beginning there will be just few sounds like rain, waves, night, summer, city ambient and whispering, but in the very next future there will be added more sound effects: for this reason the template should be fully customizable, so i prefer the use of a simple cms. * The site should provide a timer and a blog about relaxing, too. * The site should provide a login area where people can have personalized page and buy other sound effect, and in the future can provide the opportunity to add a ecommerce module. * The website must be accessible from all mobiles. * The theme/background image should be very minimal and relaxing (for example drops on windows for the rain - just an idea): i'm lookin for a more creative solution in order to mix the effects (like relax melodies app - which is a sample of what the project is going to be, but web-based/not in app).
