Should i relesase 50 backing tracks at once on cd baby or 10 at a time

Do the tracks receive the same level of promotion whether I upload them one at a time or all 50 at once on a single album? Since these are just backing tracks. Im looking at the cost of 50 track release or 5 x 10 track albums release, 1 x 50 track album release. Do it reall make a difference as its all digital. Be great to hear your opinions. I have 5 albums of backing track up there already but just 10 songs per album release.
