Depends on the artist and age of the song. I bought a couple CDs Friday night (Silje Nes, a Norwegian singer/songwriter who plays a mean guitar, and Bart Davenport, a Berkeley based singer/songwriter).
And I have bought a few songs on iTunes the last few weeks. The singles tend to be older songs that I heard on the radio or Pandora that I realized I didn’t have in my library.
I rarely by a current hit single on iTunes. There aren’t too many that I think are worth it.
