LastFM or Pandora?

I was turned onto Pandora about six months ago by a co-worker who was so excited about creating a Dave only station. I began using Pandora and thought it was great - it surely beat the pants off any radio station I could find. As time went by I stumbled onto Pandora's Jar which led me to LastFM.

After this discovery I found myself in a quandary - which one do I listen to? I read posts about this at Steve Krause's blog, David Porter's Blog and at TechCrunch. The insights offered allowed me to have a better understanding of the services; however, I still I didn't know which one was right for me.

I decided that the best way to do this was to let both services play 12 tracks for me based on similar data. Using the LastFM data from my profile I created a Pandora station that used my top 10 bands and top 10 songs as I foundation. I also decided to throw in my iTunes Party Shuffle to help see my tastes and the accuracy of the other services.

After reviewing this, my decision is that if you want more of what you currently listening to then LastFM is your place; if you want NEW MUSIC with a foundation in your current musical tastes Pandora is the ticket. If you don't want any real surprises, stay with your iTunes.
