Am i able to add old songs manually for certifications on zerocharts?

Question

i just downloaded Zero charts but i have 1300 hours of music listened to and i was wondering if i am able to add it to zerocharts since it is on my apple music library

Answer 1

when did you create your last.fm account? everything on zero works based on your data on last.fm. if you listened to those songs after creating a last.fm account, try to download the last.fm app and scan for the scrobbles. if not, you are gonna have to make the scrobbles manually but you cant do scrobbles older than 2 weeks ago...
