I found another tool that integrates with last.fm! It’s called Last Minute and it calculates in minutes how many songs your last.fm catalogs. When last.fm doesn’t have song length, it pulls from Spotify and Deezer, so it’s more accurate than most other tools that do this!
I haven’t been able to get it to work yet, unfortunately.
