I would guess around 180-200 songs per GB. It depends on the length and encoding used for the song. For a 128kbps bit rate song, it is approximately 1 MB per minute. For a 256kbps bit rate song its approximately 2MB per minute. Leave a little overhead for things like album artwork, ID3 tags, and some things to do with how drives store data (block size for one), that is about 100 minutes or 500 minutes per gigabyte. iTunes DRM protected songs are encoded at 128kbps bit rate.
painful urination , blood in the urine , or; an urgent need to urinate when it is the result of a urinary tract infection. Frequent urination may be a symptom of diabetes or can result from medications, such as diuretics. If urinary frequency occurs at night, it may be referred to as nocturia (having to urinate at night).
