There are frankly a lot of Internet radio apps that curate radio stations internationally and make use of a free database on radio-browser.info. There are only 3 that I am aware of that have worked well for me: Elisa, Foobar2000, and VLC Media Player. I wish to compare each of them in this article. I will go in order from the strongest apps to the weakest.
VLC. It is actually difficult to say whether VLC or Foobar is the best, since both have strengths and weaknesses. I’ll go with VLC in first place, since it is strong on Windows, Linux desktop, and the Android. It uses Icecast to collect its radio stations, and does the job so well, that deciding on the radio station you want out of the thousands available becomes a chore unless you know exactly what you want. The stations are available without further adjustments, but you do not get station icons or logos. The difficulty with VLC is that, even after you have curated some stations into a playlist of radio stations, and save the playlist, you still have to go hunting around your filesystem to find it again. There is no quick way to retrieve the list. Also, a strange bug is that it causes my keyboard to stop working, or at least to only work sporadically.
VLC also has an Android version which has made it my favourite media player for my smartphone. The interface is well laid-out and easy to figure out; it has internet radio which remembers your favourite stations. It can also play a variety of media formats.
Foobar2000. Foobar2000 uses radio-browser.info to serve its list, and like VLC, you get a vast list of radio stations. But this list is searchable, and if you select a station, it remembers the station the next time you run the program. Unlike VLC, your list of selected stations is automatically reloaded. Both VLC and Foobar2000 have the ability to quickly load and play a station once selected, but Foobar is the faster of the two. Under Linux, Foobar tends to bring Wayland (the replacement window server that supersedes X-Windows) to its knees, causing it to restart abruptly. This experience causes me to mistrust the stability in either OS. It is playing right now under Windows and isn’t causing problems at the moment.
Elisa is last on this list, for two reasons: it is a bear to configure for internet radio, and stations are slow to load. But its high point is that, while stations have to be manually inserted one at a time, you can load icons or logos of the stations for easier visual recognition, and after an hour or two, you can have a list of 20 or 30 of your favourite stations that will always show up when you run the program. The icons also add to the visual appeal of the app over VLC and Foobar2000. But it means you have to go to radio-browser.info yourself and get busy with copy-paste. The other downside is that Elisa appears to be an app that was made for playing stored media from your device. I have disabled the feature since I have other apps that do the job better, and primarly used it as my first internet radio app before I discovered what was in VLC and Foobar2000.
