The Last Music Library You'll Ever Need. Until the Next One.

Look out iTunes, Spotify is here.  For those of you that haven't experienced the wave of music's future, I encourage you to go to www.spotify.com and download the last music library system you will ever need.  Sure, it took a while for it to get to the US, but now that it's here, I can't imagine it going anywhere else.

What amazes me so much about Spotify, though, is that it does seem to have staying power over all the other music player start-ups that have come (and pretty much gone at this point).  MOG?  Rdio?  Last.fm?  Anyone use these any more?  Or did you ever to begin with?  I really liked Rhapsody when it came out, but why pay $10/month, when I can get Spotify's music for free?  And the radio advertisements aren't yet annoying.  I almost enjoy listening to them because I know that's the only way any of the artists are getting paid (from those advertisements).   Maybe it's just Spotify's slick interface that out-shines the rest of them.  Essentially, it feels like iTunes, just without 30-second snippets and having to purchase everything.  Instead, it's all neatly organized and F R E E, free.

So, I guess the next question is... what's going to take its place next year?  Free iTunes?
