I just made a large playlist in Roon and used TuneMyMusic to transfer it to Qobuz.
Before today, I had not fooled with playlist. I decide to make a playlist with all the Beatles recordings. I already have all their albums linked in Qobuz and Tidal, so I was careful to use only Qobuz tracks in the playlist. I included 216 tracks.
I decided it might be handy to have the playlist available in Qobuz, so I exported it from Roon to a CSV file. Then, I opened TuneMyMusic and imported the file. I exported the playlist to Qobuz. I just tried it in Qobuz and the first track of 216 started playing OK.
So, I realized I had 11 duplicate tracks. I deleted them from the playlist, uploaded to CSV, and sent to Qobuz. Piece of cake. I love it when things work as expected.
By the way, when I was deleting the 11 duplicate tracks this morning, I somehow managed to mess up my playlist. So, I did a Roon database restore from last night’s backup. It worked as expected with no issues.
