I love the Slacker and Pandora websites — free services that let you create your own radio stations that only stream music that you like. Both are very popular, and both have iPhone apps. Now Slacker has taken an interesting — and timely — new direction. Given the constraint on data usage in AT&T's new plans, the ability of Slacker Radio 2.0 (released today) to cache songs can be a convenient and money-saving feature.
