I've using Apple iTunes music playing software for about four or five years. ITunes has become the most used piece of software for playing mp3s and other audio files. It will organize all your music and you can also make play lists. Just about everyone who has a computer, whether it be a PC or a Mac, has and uses iTunes regularly. It is extremely easy to use and of course will synch up with your iPod or iPhone. Apple iTunes is a free piece of software that you can download from the Apple website. I can truly say that I don't really know anyone who doesn't use iTunes for some reason or another. I personally have all of my mp3s loaded into iTunes, and use it just about everyday when I want to listen to music on my computer. I haven't ever used another piece of software like I use iTunes, but Windows Media Player and other programs like that are similar, but aren't as user friendly and easy to use as iTunes. ITunes also has good equalization and comes it handy when you want to store EQ on certain files that may not sound as you would like on your set up. It will also show the album art work of what you listening to, and allows you to store all types of meta data within each file, including for track title, artist name, album name, year, track numbers, general comments, and more. This makes it easy to organize all of your music and no one who uses their computer to listen to music should be without it. It is free and it is clearly the most well put together program for listening to music that is available. If you don't have iTunes, I strongly recommend trying it out for yourself. I promise you won't ever go back to whatever you were using before!
