When I upload to Taxi

[jafo37]

Hello all: Hey went to upload my first submission to Taxi and made my recording into a 16 bit mp3 at 192k and after Taxi's site digitized it I heard a few pops though-out the song. I removed the song from the website and reconverted it to 16bit 128k and after re-uploading I still hear a few pops in the performance. The mp3 files sound good before I upload them but have a few small pops in them after Taxi's site digitizes them am I doing something wrong? any input would really help thanks Jafo37
