Finally looked for and found FoldPlay for my Samsung phone. I like to listen to music when I walk. I like random play. However my old music player played all MP3s including my OTR (Old Time Radio) programs and a folder of ring tones. I like to listen to OTR broadcasts at night to go to sleep… I don’t like to listen to music at bedtime. I saw no way to exclude folders. Being that I have over 700 Fibber McGee and Molly (I love those episodes, still funny after 80+ years… before my time) broadcasts there was a high likelihood that they could pop up while walking. Sometimes multiple ones in a row. I also have a folder of mp3 ringtones. So I would have to stop and press “next” to skip. I can also skip by tapping on my bluetooth headphones, but it was kind of a hassle. So most of my music is in a subfolder called…Music. So far FoldPlay is working out great.
