To try out the MP3 compatibility of the EuroLine/United, I burned a CD with a number of MP3-songs. They were encoded in different bit-rates, mono/stereo and were put in a directory structure. I also burned the CD in two sessions to see if the player would recognize multi-session CD's. All MP3's were encoded in 44,1 kHz.
Below is a table that explains the structure of the MP3 CD I made, and also information about which MP3's that played as they should.

Here is a picture of what's shown on the screen when playing MP3 CD's:
 |
As you can see, the player does not recognize MP3 files encoded in 16 kbit/s. |
So the conclusion of the MP3-capabilities of the 6620 is:
So as an MP3 player, the EuroLine/United does a pretty good job of decoding almost anything thrown at it! When it comes to the sound quality, I'm not the right person to give any comments there. To me it sounds pretty OK.
