Maybe I'm just a little bit fussy, but I prefer to have my songtitles in
Title Case, instead of plain capitals. It just seems more aesthetical to me (e.g. "Fade to Black" instead of "Fade To Black"). Now it isn't really possible to create a script for proper Title Case formatting because whether a word is capitalized depends on its grammatical function, which can only be determined for sure by the semantics (although there are cases where even Grammarians quarrel about). However, there is a set of words which can be rather confidently regarded as articles, prepositions and conjuctions as those words apear mostly as such. I collected a set of all common and many less-common words up to 4 characters length falling into this category and made a MassTagger Script out of it. I tested it on my Media Library and I guess it gives valid results for 98% of all English song titles. I thought a while on including such words as "up" and "down" in the list, which are commonly used as adverbs rather than prepositions. I didn't include words like "like" for they can appear as verbs. For the remaing 2% (mostly adverbs), you can ether correct them manually or don't care about it. The results are aesthetically pleasant anyway.
Hope someone likes my freaky script
