Pandora Radio is another popular music recommendation service. It works by streaming music similar to song suggestions entered by you, the user. You can fine-tune the suggestions by voting thumbs up or thumbs down on any given track; your positive and negative feedback affects future suggestions.
I find that Pandora offers the most useful recommendations of any online music service. That’s likely because Pandora is custodian of the Music Genome Project, which uses more than 400 different musical attributes to describe a piece of music. Pandora uses these attributes to analyze the music you listen to and match it with similar music you might like.
You can also create ad hoc radio stations by identifying an artist or track. Pandora “programs” each station with music that matches the style of the selected track or artist; an artist radio station, then, serves up music from other artists similar to the one selected.
The only downside to Pandora is the size of its music libraryjust 900,000 tracks. However, you get unlimited free access to these songs with Pandora’s iPhone app, so that’s a good thing.
