Currently to delete an account on Spotify you have to jump through hoops that many people do not bother to do.
To update any information Spotify requires you to create a completely new account (which I submitted a suggestion to be changed) and thus making it easier to leave an old account simply inactive with some bogus email.
IMAGE - not permitted in this commuity? Why?
To delete an accout a user would need to go to HELP tab, type in "deleting account" choose the right topic, click series of links, confirm throught email and once more on the website before an account is actually removed. That is just very very hard and time and energy consuming.
By providing a button on your setting to deactivate account, promptin once or twice, inserting your password - that is something other websites use, why can't you Spotify?
