Ever notice how cell phones don't just ring anymore. They all play little tunes so you know whose phone is ringing, but the song just ends up sticking in your head. Well, now that might be a good thing.

Sony has made some of its music catalogue available to be put on cell phone ringers. For about $2 US per tone, your phone could ring to tunes by Salt N Pepa, Jay-Z, or Ludacris. There is a wide range of music available, from hip-hop and r & b to country and rock, and some of it stretches back almost 50 years.

Check out the company's website, http://wireless.sonymusic.com, to see whether your phone is compatible, or to check out the tunes available.
