Nokia Music for Windows Phone - I am already subscribing to Nokia MixRadio+, can I use a Nokia MixRadio+ voucher?

Redeeming a voucher for a Nokia MixRadio+ subscription will not extend your current subscription, but simply add itself on top and run in parallel. It is therefore not advisable to redeem a voucher for Nokia MixRadio+ while you have an active subscription. Instead, cancel your subscription and wait until your current month run out before redeeming your voucher.
