Do not get indexed until i rename them and remove the numbers.
I can't seem to reproduce this, even using the exact same filename you provided:
ccstaging4:/usr/local/centovacast/var/vhosts/sc2test3/var/spool/media# mv "Shinedown - Adrenaline.mp3" "02 - lemon_and_einar_k-we_are_what_we_are_(original_mix).mp3"
ccstaging4:/usr/local/centovacast/var/vhosts/sc2test3/var/spool/media# ll

Result: OK Tracks reindexed
Can you check and make sure that your MP3 actually contains valid ID3 tags, and that they match what you expect the track to be named? My guess is that most likely the track *is* being imported, it's just being imported under a different artist/title than you expect.
You could also check your MySQL database for the "missing" track -- for example, you could use the query:
SELECT tracks.id,tracks.pathname,tracks.title,track_artists.name FROM tracks LEFT JOIN track_artists ON track_artists.id=tracks.artistid WHERE pathname LIKE '%lemon_and_einar_k%';
That will show you what track title and artist name has been assigned to the track by Centova Cast. For example, on my test server that yields:
+-------+--------------------------------------------------------------+------------+-----------+
| id | pathname | title | name |
+-------+--------------------------------------------------------------+------------+-----------+
| 50635 | 02 - lemon_and_einar_k-we_are_what_we_are_(original_mix).mp3 | Adrenaline | Shinedown |
+-------+--------------------------------------------------------------+------------+-----------+
1 row in set (0.06 sec)
And if you get NO results whatsoever, then you're correct in your assumption that the track is not being imported at all.
