What's a site that allows you to upload an mp3 to share? See self-text.
I tried jumpshare.com a minute ago but after I uploaded the file - the fucking site said the link dies in 24 hours unless I sign up. whyp.it is the same.
I was going to suggest put.icu (seems like max 4GB) but their max expiry is 1 day. I found a list of privatebin instances here (it's a pastebin but you can also attach files). From the table, you can select ones with file upload, but some of them have quite low file size limit. I was able to upload a 10 MB file over at https://privatebin.at.
