Buy MP3's Cheap... $1.00-$5.00 per album...

Here are a few sites like allofmp3 that sell cheap mp3's. You can buy a full album for $1.00-5.00 depending on the bitrate and how many songs there are. Everything is priced based on bitrate and total size. I use mp3sparks and don't have any problems. They offer 128-386kbps cbr and vbr, lossless, and other formats.
