One might think (if one thought quickly) that, with all of the access to information provided by the internet, it would be easy to learn about new music. This might seem especially true if we compare it to the way we used to learn about artists and songs (from friends, print magazines, fanzines, the radio, MTV). Each one of these categories could be hit-or-miss (a friend might have bad taste, certain artists could dominate the radio just as genres would dominate MTV).
Yet, we (or at least I) developed strategies for coping with these–you know which friends have tastes like your own (and the other friends might actually broaden your horizons); you can change radio stations or listen selectively to MTV (not that this is an issue any more since MTV no longer plays music). But today the situation is just damned overwhelming. I have been burned by algorithmic suggestions from Pandora, perplexed by “people who buy this also buy…” from Amazon, and similar (even less helpful) suggestions from iTunes store and the ironically named “Genius” app.
