Death of itunes

I have 10 of thousands of songs with me, and in a long run, i believe everyone will own those many songs. With apple charging more than a $1 for a song, its next to impossible for my entire music collection to come from this source.

Apple has to change its business model (similar to lala or Rhapsody, where you can add songs to your collection for much lesser price) or Apple's itunes will die soon.
