Occasionally my wife listens to music on our headphones on the computer and wants me to download a song or two for her. I rarely download music, but instead I just buy the CD, but for her one or two songs
Amazon MP3 Downloads works fine at .99¢ each.
I was poking around some of our affiliates and noticed we have
emusic.com listed, yet I am not that familiar with them. It appears their songs are only .89¢ with some only being .49¢ ... so I may have a new place to download music for her. It looks like they are also offering a $25 credit right now when you join.
They also offer a
daily download for free and downloadable
Audiobooks.
For those wanting to download albums or single tracks in higher resolutions FLAC (up to 192/24)... then
HDtracks.com is a great source. Of course those will cost a little more.
