Yup, can understand if your library is small, but for bigger libraries that's definitely the most inconvenient thing you can do.

Speaking from experience because I was basically forced to do it that way when I didn't have regular internet access yet. My library was longer than 50 days. Just Hip-Hop alone was above 100GB.

I used to find a shitton of music that way, but the inconvenience was real. Worst was music that I had to tag myself for example. Love mp3tag but that's shit.

I find it inconvenient to have limited skips and depend on one service to give you the song you want with the version you want. Also spotify ui doesn't make sense to me, things just don't work at times. Not to mention the ads.
