Sony announced that they would be launching their own online music service later this year. The 500,000 song service known as "Connect" will be priced similarly to the competition at $1/song. The new service, however, will initially be limited to work with only Sony devices and the songs will come in Sony's proprietary ATRAC3 compression format. In related news, Sony also announced a high-capacity version of its Mini-Disc (MD) which brings the Mini-Disc capacity to 45 hours. While the number of online music stores continue to grow, Apple's appears to be the most successful. Apple announced on Tuesday that the iTunes Music store currently has 70% marketshare of the legal music download services according to the latest numbers from SoundScan. Apple also announced that they had sold over 30 million songs from the iTunes Music Store.
