Your API returns a different play_count than you display on your website.
Example Website:
https://soundcloud.com/esbee/aleah-water-and-wine-stefan-biniak-privat
You can use their v2 api: https://api-v2.soundcloud.com/tracks/260065214?client_id=ADD_YOURS Which lists the play count at a proper 10300+
However there doesn't seem to be any documentation about it.
