Thanks for the reply. I looked at classical again. I was wrong, the entries are not rock music, but mostly movie soundtracks. I think I would mostly use this type of tool for popular music. I manage to discover a lot of classical on my own, as known orchestras and artists constantly pick up new works to perform. Popular music takes more effort, as the performers are constantly changing.
The browsers I use are Mozilla Firefox (previous attempts and now) and Google Chrome, both the latest available through the repos. I use the latest Fedora Linux operating system, currently 37.
