revealing all thumbed up tracks but in separate thread
execution no longer in parallel but track collection is broken
no longer "normalizing" artist for thumbed-up tracks because split was failing on "2002" artist.
No longer attempting to call split() on numerical artist name
Normalizing both track title and artist now. Preferably this should be done when searching for song and only after fail to find it.
update indenting, add loading and fix a bug
upgrade to jquery 2.0.3
modify the error message
