Songs on Pandora

I've been listening a lot to songs on the Pandora app and notice that it gives info (e.g. 1998 remaster) and when comparing it to the same album and song on Spotify, the same info isn't there. (And probably the same is true on CD). So if you have the app, you can look up a song and potentially find more info. Sometimes the song will say something like "single version", "re-recording", "remix". Obviously, a re-recording would be evident to any of us. But this info can be helpful, too.

Sometimes, though, I find "single version" a bit misleading, when the album version isn't different. I think what's going on there is that for reissued CDs which included bonus cuts with 12" versions, they distinguished the other version on the album as "single version" or even "album version".
