If you aren’t checking in with the music at Bandcamp… well, you should be.
So far, most of the music I have downloaded from Bandcamp comes from Projekt. Bandcamp’s Feed and Discover features can help you find new (or at least, new to you) music and you can preview most of the music in its entirety, not just a 30- or 90-second sample.
The music is downloadable in multiple formats, including FLAC. They also sell actual CDs as well, when they are available. Oh, and I cannot talk about Bandcamp without mentioning the live, continuously updated display of the most recently sold music. Very cool.
Don’t just take my word for it, go check them out now. I’m sure you’ll find something your ears will beg you to download.
