Plex's Winamp-inspired music player Plexamp is now free | TechCrunch

Eh, I like Plexamp’s features, but the app is not exactly free, more “freemium.” All the compelling features that you’d want to use it for are behind the subscription paywall. DJ, track and album radio, the unique features aren’t free.

Also, at least on iOS the app feels clunky and sluggish with long delays when skipping, scrubbing, playing, and pausing. (EDIT - turns out this is specifically an issue when using Airplay, it's fine for local playback).

My wife uses Plexamp on desktop (Mac and PC) and it seems good there. I personally tend to use the WiiM app for Wiim mini with Asset UPnP server.
