Import Last.fm scrobbles #30

Closed durnezj closed 2 years ago

durnezj commented 3 years ago

Hello, I recently came onto this software because I was planning on building similar statistics for my own listening history, based on my last.fm scrobbles. However this web interface seems to have everything I need already. The problem is that I have over 10 years of last.fm scrobbles (48k+in total) and I would like to import them into this software. I use This Node.js tool to export them to my own servers. At first glance it seems like adding each scrobble as a datapoint would be enough for your-spotify to pick them up. Is this a correct assumption? How is the database constructed from the Spotify API? The goal is that I will script something together that can import my last.fm history into this dashboard as well. In the future this could even become a feature of this application.

I really like this idea actually. The database is constructed from Spotify data, ids are Spotify ids, etc. For your thing to work, you would need to link a specific song to a Spotify song ID, by using the search API request for example. For every song, I then grab the album and the whole artist if they do not exist in the database. So, for a single Spotify song ID, I request Spotify 3 times (the song, the album, the artist) depending on if the resources already exist in the database. The interesting stuff begins here I computed the missing track ids in the database and will query everything I need. So for your thing to work, I would take from line 164 to the end of the function, with missingTrackIds being all your lastfm track converted to Spotify IDs.

I hope I have been clear and simple enough, please keep in touch if you have any trouble achieving this or if you want more information. Good luck!

Thanks for the detailed explanation! It actually seems doable after all. When time permits me in the future, I would love to take a shot at this.

Hey! It's been a while here. Last release implements full privacy import. This means that you can now import from privacy (1 year of data) and full privacy (data since account creation). I feel like you can actually import the data you want from those two already. I don't think I'm going to work on this in the near future. If anyone gets interested in implementing this I will consider it but not for the moment. Thanks for your understanding.

Hi, thanks for giving me a heads up! I still have not been able to find the time to invest into looking at a solution, and I'm not sure I will due to a busy period in my non-programming life. I have only been backing up my own last.fm scrobbles to my own database. I still need to couple them to the spotify equivalent of the song. As long as this repo stays up I can have the inspiration where to start if I find the time on a rainy sunday afternoon :wink:
