One of the great treasures out there in the cloud is the Internet Archive.  I contains terabytes of music, movies that have fallen into the public domain, rare voice recordings, and the Wayback Machine.   It's a great place to explore on a rainy day.  
I've downloaded a lot of music from the Archive and offer this tip:

• When viewing music on the Internet Archive, look for the "VBR ZIP" link on the left side of the page. It's a single .zip file that contains the entire live music presentation as variable bit rate MP3 files. Download, unzip, and you've got the entire show.
• Some recordings are marked "stream only", which might lead you to think they cannot be downloaded. But they can, and here's how.
• On the left, where it says "listen to audio", RIGHT CLICK one of the M3U file links. The VBR link will have the best sound.
• Save the M3U file to your computer.

A M3U file is a list of sound files that audio players read as a playlist. WGET, a common utility, can read M3U files and download the contents.     WGET is included with Mac OS/X and most Linux distributions. Windows users can download a free copy from http://gnuwin32.sourceforge.net/packages/wget.htm

• Windows users:
• To use WGET, open a command window:
• create a folder into which you want to download the files (e.g., "mkdir downloads")
• go into the folder (e.g., "cd downloads")
• type "wget -i thefilename.m3u", where thefilename.m3u is the file you just downloaded.
• when the downloads finish, copy the mp3 files into your music folder.
• When done, move the mp3 files into your music directory.
