Unknown artist bug in iTunes Match/iPhone 4

I got around the bug by changing the name slightly. Santana was "unknown" and I added a space after Santana in iTunes and now it shows Santana on the iPhone. You can't see the space and can still search for Santana so it isn't a huge sacrifice. Interestingly enough if I put it back to original name without the space then it comes back as Unknown. It only has the issue on the iPhone and not on my other computers with iTunes.

I tried simply adding the artist name to album artist field and updating and all, didn't work. What did work, without any real work was I simply changed the name for the artist (in artist view), and added a space 1, let iCloud sync up with Match right there not just a few seconds after changing it, then changed it back and took the space and 1 off and they were then updated correctly with the right artist name.

same here/ adding the space after the name sometimes helps, sometimes not

Any update on this? It has been giving me problems as well all of a sudden (today). The songs I am trying to import (my band) have ALL the info filled out and showing in iTunes, but I can ONLY find them by track name only on my iphone, nothing shows up under artist. Nothing has changed on my computer.

I am on the latest iTunes version 10.5.2.11.

I had this exact same unknown artist issue and managed to fix it. Unfortunately I did a bunch of things all at the same time - I don't know if it was just one of them, or the combination of all, that made it work.

Here's what I did:

1. Disable iTunes Match on my mac
2. Reboot my mac
3. Backup and restore my iPhone using iTunes
4. Resync my iPhone to reload all my music

Painful, probably over the top, shouldn't be necessary, but it worked.

This was happening to me and all my tags are fine. I don't use iTunes Match (yet), so I went into my iphone Settings --> Music and saw that "Group by Album Artist" was set to "ON".

I turned this option to "OFF" and now everything appears in the artist list! YAY.

Easy fix.

I don't think this is the solution. I like the "Group by Album Artist" because it's very useful.

In my previous iPhone 4 it worked well with no problem. My iPad can also handle all artists, but the new iPhone 4 (about week old) shows about 10% of unknown artists (Aerosmith, The Beatles, etc.). There must be some problem on iCloud. Hopefully Apple will fix it soon.

So I've tried many thing (same/similar) as ChzPlz posted. What worked for me was restoring my iPhone via iTunes (DFU restore). Now I don't have any unknown artists 🙂

Thanks, this worked for me when nothing else did.

Simple. Worked perfectly. Not sure why it became switched on!🙂

Same issue here. Not sorting by album Album artist helps. But it´s still very annoying. I allways thought it´s the details that matter to Apple still this apparently doesn´t apply to iTunes match. Album art is not showing for many of my albums either. This should be fixed.

I know this is an old thread but what TomDac said worked! Turning 'Group by Artist' OFF in the settings on the device. I have a feeling its because I haven't updated to iOS 6 and I don't want to do that. So thank you so much!
