Hello Beej75,
After reviewing your post, it seems like the alarm is not playing sound from the song selected. There are a couple things you can try that may be able to help. We would recommend you read this article for more information.
Does it play the song in the alarm if you choose a different song?
If you delete the alarm and recreate it, does it play the song?
Was this song downloaded from the iTunes Store or Apple Music?
"Do Not Disturb and the Ring/Silent switch don't affect the alarm sound. If you set your Ring/Silent switch to Silent or turn on Do Not Disturb, the alarm still sounds.
If you have an alarm that doesn't sound or is too quiet, or if your iPhone only vibrates, check the following:
- Set the volume on your iPhone. If your alarm volume is too low or too loud, press the volume button up or down to adjust it. You can also go to Settings > Sounds & Haptics and drag the slider under Ringer and Alerts.
- If your alarm only vibrates, make sure that your alarm sound isn't set to None. Open the Clock app, tap the Alarm tab, then tap Edit. Tap the alarm, then tap Sound and choose a Sound."
