BOSTON ( TheStreet) -- With commerce at your keyboard, spending a day shopping online sounds more peaceful than fighting crowds at the go-to stores. 1. Lala.com: Can a site funded by Bain Capital and propped up by Warner Music Group be considered a "hidden gem?" Considering that Google and Facebook are just catching on to what a lot of Lala listeners already know -- that sometimes a song's only worth a dime -- Lala's reach isn't yet as broad as its big backers would indicate. Here's the basic model: Listen to a full song once for free, a Web-only version costs you 10 cents and a mp3 file goes for 79 cents. Instead of going for the bargain bin, create a custom mix for your friend. If he doesn't like the tunes you picked, he can swap them for new ones.
