So, Friday is supposed to be the day for Web Stuff and Monday is for Music, so here is a day devoted to some Web sites devoted to music.
My musical self is like a shark. If it doesn't keep moving forward, I feel like it dies a little. These sites help me move forward musically.
Useful Noise is a blog about music of the aughts. I know the music isn't actually new, but much of it is new to me, so it counts.
Chris Hanaka has a blog that regularly opens my ears to great music. Tons of embedded songs, so I spend most of my time on the site actually listening to music--not reading about it.
Music Uncovered and Covered is basically a sub-site by Hanaka that focuses on song covers. I love covers.
