Some mp3 files from online services do not play

[bluenite]

When you download an mp3s (free option) from online archives such as Spotify, Youtube and similar, they cannot be played. There are no 0 size, seems like a normal audio file. Are they somehow locked or protected? "Preview" quality is enough to hear before a possible purchase.
Can anything be done with this?
thanks for advice

a) wrong subforum. You probably want Prime Time (mp3 clinic is about posting your OWN mixes for feedback and review)
b) Careful. Advocating piracy can get you banned.
