I have many MP3s of songs in Hebrew. The tags are in Hebrew, auto-populated by Windows Media Player when I rip the CD. Windows uses the Windows Hebrew code-page (1255), which apparently Google Music doesn't like, because all the Hebrew tags come out in gibberish.
I am a fluent Hebrew speaker, and the mp3s are songs that I ripped myself (from CDs that I own), and for which I edited the tags myself, using Windows Media Player. I know how to automatically convert the code-page of an ID3 tag on my local hard disk, but not for what's already uploaded to Google Music.
When I change the code-page to the Mac Hebrew code-page (10005) before uploading to Google Music, the Hebrew comes out fine.
Is there any way to change the codepage of MP3s that I've already uploaded, or do I have to remove them and re-upload them?
