Write some Software

Hi, I'm trying to track the activity of a number of artists in social media, for that, I think a spreadsheet scheme would be useful. First spreadsheet, info about the artist, his name and facebook, twitter, instagram, snapchat, spotify, youtube links from where the info would be taken and processed, in the case of youtube and spotify I'd like it to open a new cell to punctuate songs independently each time they upload a new one and to be able to delete and add songs manually or automatically after 3 months. Second, a punctuation will be made based on artist social media presence following a formula provided by me; for example if he gets +1 follower in twitter he will get +3 points; I need this to be easy to modify so I can change the punctuation rules. Third, I need the punctuation of each artist and its songs ordered in a ranking and easy to read. Thank you
