Windows: If you use iTunes to load up your iPod and other Apple devices but otherwise aren't a fan of it — especially the slow and sometimes quirky importing — SYNCiTunes imports and synchronises music into iTunes, sans actually using iTunes.
SYNCiTunes injects your music into your iTunes library with a fair degree of fine control over the process including the ability to exclude albums with missing data, files already in iTunes, and more — as seen in the screenshot above. SYNCiTunes will also update tag changes made outside of iTunes which is great for those of us who don't like doing any serious tag editing in iTunes.
SYNCiTunes is freeware, portable and Windows only. Have a favourite program to supplement iTunes or totally replace it? Let's hear about it in the comments.
