Not remotely close. Plexamp dies have the same radio features Spotify has and they have their purpose, but those “Guest DJs” as Plexamp calls them are different.
First of all, song radios do very often just include roughly the same styles of the original song, mix them up a bit. This specific “guest DJ” holds the style almost exactly if at all possible with the songs you have access to.
Secondly, it is not a Radio. It injects itself into a running playlist (which can be generated by sonic analysis as well, different topic). So you’d have your regular playlist going, notice that the style of that one song that’s playing right now is exactly what you want now, have it hold the style and when You’re getting tired of it,.you switch it off and the regular playlist will continue.
Plex does a rather comprehensive analysis of audio (if you have Plex pass that is) and is then able to do some really cool stuff regarding playlists and such. One of those things is a mode where it keeps injecting songs that have the same vibe as the current song until you switch it off again at which point it’ll just go on with the playlist. It dies that surprisingly well.
Works for local audio on a Plex server capable of doing the analysis (no ARM support ATM) and for Tidal.
Spotify would just play the same.few things over and over and over after a while for me. Especially since their algorithm will bend over backwards to only play 1-2 songs per album.
With the features of plexamp I regularly get songs I’d go “ouh, haven’t heard that one in quite a while” about.
That might be only me though. I encourage everyone to try plexamp with tidal for one month (which is free on tidal, not for plexamp). The free version of plexamp lacks many of the features, sadly.
