I constantly find my Release Radar recommending songs by an artist (say A) with the same name as an artist (say A') that I might actually wanna listen to. This is extremely dumb as an issue because these two artists are listed as genuinely different artists in Spotify and the newly recommended song by a wrong artist is listed as a song of A' in the system. A reasonable conclusion is that at least Release Radar does not look into the artist IDs but just merely refers to their names. This happens to like 5 different artists to me and my Release Radar is contaminated by songs which I have absolutely no interest in. I believe this is a very basic bug that can be fixed in like 5 minutes.
Here's an as short as possible version of a previous post in this thread, explaining the behavior of the Release Radar.
