Song titles
Well, these are pretty much all of the tips I can think of right now:
1) One of the main components of making good song titles is definitely evading (as much as possible, but not always) names beginning with "The" and formations in the pattern of "(noun) Of (noun)" (for example "Beginning of Spring"), or combinations of the two. Names with "And" or "For" in the middle aren't that good, either. These names are actually the most common, and as such sound a lot less attractive than names that use some other connective words.
2) If using one-word titles, it's often good to use some more obscure words (scientific terms, less commomly used words in general), because it will look better due to our innate curiosity.
3) Some drama can never hurt, so the use of words that sound absolute (like never, always, everywhere, forever, etc.) is also a good way to make good song titles.
4) Ending song titles without finishing a thought (or simply adding "...") at the end can make a song intriguing, just don't overdo it. You don't want your audio page to be littered with dots, do you?
5) Also, proper use of stuff like alliteration and assonance (Wikipedia links) can make song titles much more "pleasent to the ears", and will make them sound a lot better.
