Anyway, took a 50 free downloads trial at eMusic and quickly found more than 50 MP3s that i'd want. Thus, i went ahead and subscribed. However, the way the subscription works, it's less expensive if i download all the songs i want during one month. Thus, i'm asking for music recommendations from you people.
eMusic's catalog is much better for post-2003 than before, but i'll try whatever you recommend. As for my tastes, i don't do pure country, hip-hop, reggae, or opera, although if they're fused with other things, than it might be fine. In fact, songs that are fusions of lots of different varieties of music (e.g. jazz/blues-rock/funk, pop/ska/gospel, or Metallica as interpreted by 4 Finnish cellists) are often my favorites. You can also refer to this geeky list of favorite songs i compiled 3 years ago.
Thus far, my best discoveries at eMusic have been Gov't Mule, Danko Jones, The New Pornographers, and Nick Cave & The Bad Seeds' Abattoir Blues album. I was at least vaguely familiar with all those before (except Danko Jones), but i didn't realize how great some of their music was.
I'm particularly addicted to Gov't Mule's Mr. Man and The New Pornographers' Star Bodies.
