When a listener uses the request form to put in a request, instead of it just saying:

"Your song request has been submitted - thank you"

Would it be possible to have state something like:

"Your song request has been submitted and will play in "minutes here""
(which would be given by whatever time one has set for requests to play. )

This gives the listener an idea of when their song will be played.

i think this is a great idea,i had few listeners emailing asking me when they request will play etc..so i think showing a time after there request is  very good idea...
