Most streaming sites compress heavily aiming for peaks at between -12 & -8 dBs. It it worthwhile finding out what a site runs at and mastering for them specifically to avoid such issues - something I've only recently learned.
Normalizing is rarely a good option - it's suppose to raise the loudest parts to the allowable maximum and bring everything up in proportion to that but it rarely works that simply and the way items in the mix sound can change dramatically based on the playback device, the amp and speakers.
Posting only one song at a time also helps forum members share the listening and feedback load too.
