Happen upon "Trip to the Moon (Club Remix)" by Nina, Goddess of Dance on FlashFlashRevolution, decide I like it.
Find a promo site from the artist featuring the music video. Follow the "click here to download the song" link only to find a broken page.
Go to MP3.com and search for the song. Find that it's only available in either proprietary formats, or from vendors who make you install their software.
Google it. Find a site that'll stream it for free but nowhere you can just GET the stupid thing and not suck up everybody's bandwidth.
Slap the internet for its insistence on being stoopid.
Go back to what I was already listening to, without having given any support to the artist, or getting the song I wanted.
