If the learning curve for omxplayergui seems too steep, you could use VLC. An enhanced and accelerated version of this is now available to Raspberry Pi users by entering "sudo apt install vlc" into a Terminal after first updating and upgrading by typing "sudo apt update" and then "sudo apt dist-upgrade". Radio Titles and Stations are entered into a Textfile in a slightly different way:
#EXTINF:-1,Old School HipHop/RnB
#EXTINF:-1,UK top 40
#EXTINF:-1,The Rock! (Hard Rock)
The file is saved with .m3u at the end e.g. Radiostations.m3u. To play the radio stations you left click on the file wherever you have stored it , scroll down to "Open With", right click on "VLC Media Player", mover up and down your playlist and then select with right mouse click.
