There are a few artists who started on WL then went DeMu, and they just reuploaded their WL tracks self-hosted. If you want to delete your stuff from WL, that's up to you, but I'd say there's no harm in having songs uploaded in multiple places. DJs and listeners can see where a track was uploaded on LNBeats, V4V Music or by looking at the value splits in the RSS feed. 💜
