Doctor Tunes is a small automated Music metadata download tool: it will scan your music library filling the missing music tags and normalizing the existing ones.
with Doctor Tunes you can:
- fill and correct year and genre
- download album artwork (only when it is not present)
- normalize artist and album name
An example: i personally developed and use this app to fill year and genre on my music library and to be able to filter and understand my music.*
If you need Doctor Tunes and think that 1.5$ is a fair price to pay for such useful thing, you can find it on the Mac App Store:
