VPN needed for using Soulseek?

Hiya,

Working on completely replacing Spotify completely. Soulseek has popped up a few times here and there among forums and here on lemmy, so I thought I'd give that a go. I've started with getting Nicotine+ client and seems to be working fine. However, what does the traffic look like when downloading/uploading things over the Soulseek network? I read its peer-to-peer network, but does that mean I don't need a VPN? I'm also told to open a port on my router, I'm assuming this is so that I can share my own library with the rest of the network, but how safe is this?

If anyone could help my clarify this I'd greatly appreciate it!

Edit: Just found this very promising project too! https://github.com/slskd/slskd
