Symptoms of a Tailbone Injury. The most common symptoms of a tailbone injury are tenderness and pain when sitting or applying direct pressure to the coccyx.

The average file size for a song that long is about 4mb, add or take 1mb. The size of each song depends on its quality, or bitrate. Your songs may be of CD quality bitrate, which is 1,411.2kbits/s, compared to MP3 quality, which is 128 or 192. There are file types with qualities everywhere in between. Generally, you might notice a small difference in quality if you go down from CD to MP3.
The length of a career can vary greatly of course, let's say anywhere from 5 to 50 years, giving us a range of 50 to 1000 songs. This would put the total number of songs somewhere between 1 and 20 billion. I would put my guess towards the lower end of that scale as I think the median number of songs per artist would probably be in the 100 - 250 range. So my answer to this question is: Somewhere in the neighborhood of 2 - 5 billion.
