Recently, I wrote a chrome plugin that saves information of all of the songs I listen to on youtube to amazon since youtube's history API is shit. Theoretically, I could write a nightly job that runs YouTube-dl to turn all of those videos into MP3s. Taking it even further, I could run a nightly SyncMe job on my phone to copy the MP3s locally. A setup like this would be good for people with limited phone bandwidth. Imagine not having to search out MP3s anymore. Is it still considered pirating if a robot does it?
