Yes. Radio Horizonte plays old obscure songs, including old AOR songs. You won't find only obscure trash music, AOR music too. Any kind of music. You can go to Google Play, download the app Horizonte 94.3 and enjoy. I want to tell you that my intention is not to spam, I am only telling you about an Argentinian Internet radio station that plays any kind of music.
This radio station started on 1986 and "died" on 2001, being now Radio Disney, but I remember those times where I frequently dialed this radio station (94.3). I had prepared a virgin cassette. When an interesting song started to play, I pressed the red REC button. I still have a collection of old cassettes stored in a box with recording from the old Horizonte 94.3 radio station!!!
