Soundcloud limiting downloads without a subscription is news to me, but I've had a subscription for about nine months now, mainly to have the extra space and not need to delete things or make an extra account. I don't mind the extra stats but the only ones I really look at are the geographics.
Without Soundcloud Premium Solo (or above), each song can only be downloaded 100 times. You need to pay 9 Euros a month (or 79 a year) for unlimited free downloads of your songs.
