Gotham Gal has posted a great list of albums from 2005. I found a couple other good lists here, and here.
All of these great year-end music lists got me to thinking that subscription-based music services like Rhapsody are totally worth it if you like to listen to a lot of new music. All but one of the albums on the Gotham Gal list (the Bright Eyes album) are available on Rhapsody. I dumped all of the other albums from her list into a Rhapsody playlist and – bam! – just like that, I’m enjoying all kinds of new tunes for less than the cost of a CD.
