I wish there were a way to put the chip & antenna inside (or behind?) the watch casing.

While this is really impressive, putting something in front of the faceplate breaks the great F-91W look and feel for me.

Or just forget the watch and casing and build an add-on to the strap to hold the NFC chip. This should work with any watch strap that isn't metal.

Similar project I did to carry a microSD memory card.

Projects like ollee Watch seem to be able to stash it behind the front crystal or underneath the LCD.

Ollee does that by replacing the original PCB. In this project the movement is kept original.

I recall the blog n-o-d-e did successfully put an NFC chip inside while also retaining the default PCB, so there is at least some free space in the case...

I wonder if they provide this data if you do a "download your information" request. I remember some discussion about how much info that archive had:

Last.fm is great! I do like the breakdowns you can do there, especially the query for the top songs/artists of the last 30 days, year & all time.

It's not as seamless to jump in and listen to stuff on lastfm though.

It's annoying they don't allow migrating in a data dump from Spotify (they do, but everything is tagged as listened to on the day of import...). My Spotify account is 10 years old but I only discovered Last.fm ~ 6 months ago.

Oh this is great, i might run this over my backups to retain the artists/titles as well.

It is relatively easy (currently) to take a playlist and back it up as a plain text file.

CTRL+A, CTRL+C from web or desktop puts a newline separated plain text list of songs on your clipboard.

Main risk is that the list is in the format of "https[:]//open[.]spotify[.]com/track/[song-id]", so Spotify may break the lookup of these IDs in the future.

> so Spotify may break the lookup of these IDs in the future.

Luckily, Spotify seems pretty good at backwards compatibility. `spotify:user:$username` still seems to work in the search-bar, must have worked for almost 20 years now, and given that artists themselves use those track URIs and IDs, I'm sure Spotify will be even more careful with those than search query syntax.
