Spotify USER ID string lengths are not all the same - be aware developers

[GB122]

This situation came up with my own app so just warning others - I was storing USER ID, USER NAME, and ACCESS TOKEN in a mysql database but noticed that some users were not able to use my app and others were. Turns out I traced it back to a situation where mysql just assigned a default max string length (of 24) for the USER_ID field based on the first USER ID entered.  Unlike Track IDS and album IDs, etc, USER IDs are NOT all 24 chars long - some are 26 or 27 chars or 23 or whatever.
