I purchased a Diamond Rio and quickly realized I needed quality software to collect and organize mp3 songs (I've since switched over to a Nomad II and since Music Match has plug-in's for both I can use all the mp3 music I had organized for the Rio immediately with the Nomad II). One thing you find out when you start to accumulate a lot of mp3 files on disk is that the disk directory structure and directory and file names is important if you ever lose your database or want to move the files around on disk or to another disk (especially if you are going to "rip" a lot of CDs so you have them available to quickly download to a mp3 player). Music Match allows you to create a very organized disk directory structure to hold all your songs. For a given mp3 file ripped from a CD, the file is stored under the artist folder, then the album folder. This is more important that one would at first realize because it is often necessary to move the files around and then re-import them back into the music database. Music Match makes this trivial and it's easy to find your music on disk even if something happens to the Music Match database, you can just start over and import all or some of the files within minutes. This became very useful when I started to fill my hard drive and decided to use a re-writable CD in my CD burner to hold some of my music files. In a few minutes I was able to copy several complete artist directory structures to the CD, and re-import the songs back into the Music Match database. I guess I appreciated this all the more because I started off with Real Jukebox which stores all the mp3 files in a single directory by default and the original track order of a CD was lost once the CD was ripped so moving the files was tedious and retaining the original CD track order required creating a playlist for each CD (too much work!). Once you load the music to disk, Music Match lets you sort your songs by artist, album and original track order among others.
It's also very fast at ripping CDs and you can also burn new custom CDs from a playlist of mp3 files if you have a CD rom burner. This program really brings it all together. You can collect mp3 files either by download or ripping CDs. It's then easy to create playlist of any order to download to a mp3 player or burn a custom CD. This program is all you really need.
