I mean there’s a whole block on this:

Lidarr is just a tool. Like any tool, it can be misused. Yes, people could point it at less-than-legal sources. No, I’m not telling you to do that. If you want to support artists, buy their work. If you don’t, don’t pretend Spotify streams are “support.”

Important Note: Always ensure you’re obtaining music through legal channels such as:

• Digital purchases (Bandcamp, iTunes, Amazon, etc.)
• Ripping CDs you’ve purchased
• Free legal downloads offered by artists
• Music available under Creative Commons licenses

And yes, I’ll use this with my existing, mostly legally obtained, music collection. I don’t mind the pirate stack though, it’s far easier to just download the album than ripping your vinyl and tapes.
